Comparison of Julia's Symbolics.jl vs SymPy for Symbolic Computation

Symbolics.jl is a symbolic modeling language for Julia, built in Julia. Its goal is very different from Sympy: it was made to support symbolic-numerics, the combination of symbolic computing with numerical methods to allow for extreme performance computing that would not be possible without modifying the model. Because of this, Symbolics.jl excels in many areas due to purposeful design decisions:

  • Performance: Symbolics.jl is built in Julia, whereas SymPy was built in Python. Thus, the performance bar for Symbolics.jl is much higher. Symbolics.jl started because SymPy was far too slow and SymEngine was far too inflexible for the projects they were doing. Performance is key to Symbolics.jl. If you find any performance issues, please file an issue.
  • build_function: lambdify is “fine” for some people, but if you're building a super fast MPI-enabled Julia/C/Fortran simulation code, having a function that hits the Python interpreter is less than optimal. By default, build_function builds fast JIT-compiled functions due to being in Julia. However, it has support for things like static arrays, non-allocating functions via mutation, fast functions on sparse matrices and arrays of arrays, etc.: all core details of doing high performance computing.
  • Parallelism: Symbolics.jl has pervasive parallelism. The symbolic simplification via SymbolicUtils.jl has built-in parallelism, Symbolics.jl builds functions that parallelize across threads. Symbolics.jl is compatible with GPU libraries like CUDA.jl.
  • Extensible: Symbolics.jl and its underlying tools are written in pure Julia. Want to add new or better simplification rules? Add some Julia code! Need to add new derivatives? Add some Julia code! You get the picture. Breaking down these barriers makes it easier for the user to tailor the program to their needs and accelerates the development of the library.
  • Deep integration with the Julia ecosystem: Symbolics.jl's integration with neural networks is not the only thing that's deep. Symbolics.jl is built with the same philosophy as other SciML packages, eschewing “monorepos” for a distributed development approach that ties together the work of many developers. The differentiation parts utilize tools from automatic differentiation libraries, all linear algebra functionality comes from tracing Julia Base itself, symbolic rewriting (simplification and substitution) comes from SymbolicUtils.jl, parallelism comes from Julia Base libraries, Dagger.jl, etc. SciML Tools like DataDrivenDiffEq.jl can reconstruct symbolic expressions from neural networks and data, while NeuralPDE.jl can automatically solve partial differential equations from symbolic descriptions using physics-informed neural networks. The list keeps going. All told, by design Symbolics.jl's development moves fast because it's effectively using the work of hundreds of Julia developers, allowing it to grow fast.
  • While Symbolics.jl has many features missing from SymPy, it does not superset SymPy's functionality. For a list of missing features, see this issue.

Feature Summary

Because Symbolics.jl is built into the Julia language and works with its dispatches, generic functions in Base Julia will work with symbolic expressions! Make matrices of symbolic expressions and multiply them: it will just work. Take the LU-factorization. Etc. Thus, see the Julia Documentation for a large list of functionality available in Symbolics.jl.

A general list of the features is:

and much more.

_build_function(target::JuliaTarget, rhss::AbstractArray, args...;

Arguments:

  • ex: The Num to compile
  • args: The arguments of the function
  • expression: Whether to generate code or whether to generate the compiled form. By default, expression = Val{true}, which means that the code for the function is returned. If Val{false}, then the returned value is compiled.

Keyword Arguments:

  • target: The output target of the compilation process. Possible options are:
    • JuliaTarget: Generates a Julia function
    • CTarget: Generates a C function
    • StanTarget: Generates a function for compiling with the Stan probabilistic programming language
    • MATLABTarget: Generates an anonymous function for use in MATLAB and Octave environments
  • parallel: The kind of parallelism to use in the generated function. Defaults to SerialForm(), i.e. no parallelism, if ex is a single expression or an array containing <= 1500 non-zero expressions. If ex is an array of > 1500 non-zero expressions, then ShardedForm(80, 4) is used. See below for more on ShardedForm. Note that the parallel forms are not exported and thus need to be chosen like Symbolics.SerialForm(). The choices are:
    • SerialForm(): Serial execution.
    • ShardedForm(cutoff, ncalls): splits the output function into sub-functions which contain at most cutoff number of output rhss. These sub-functions are called by the top-level function that buildfunction returns. This helps in reducing the compile time of the generated function.
    • MultithreadedForm(): Multithreaded execution with a static split, evenly splitting the number of expressions per thread.
  • fname: Used by some targets for the name of the function in the target space.

Generates a Julia function which can then be utilized for further evaluations. If expression=Val{false}, the return is a Julia function which utilizes RuntimeGeneratedFunctions.jl to be free of world-age issues.

If the rhss is a scalar, the generated function is a function with a scalar output.

  • checkbounds: For whether to enable bounds checking inside the generated function. Defaults to false, meaning that @inbounds is applied.
  • linenumbers: Determines whether the generated function expression retains the line numbers. Defaults to true.
  • convert_oop: Determines whether the OOP version should try to convert the output to match the type of the first input. This is useful for cases like LabelledArrays or other array types that carry extra information. Defaults to true.
  • force_SA: Forces the output of the OOP version to be a StaticArray. Defaults to false, and outputs a static array when the first argument is a static array.
  • skipzeros: Whether to skip filling zeros in the in-place version if the filling function is 0.
  • fillzeros: Whether to perform fill(out,0) before the calculations to ensure safety with skipzeros.

Adding Analytical Derivatives

There are many derivatives pre-defined by DiffRules.jl. For example,

using Symbolics
 @variables x y z
 f(x,y,z) = x^2 + sin(x+y) - z
f (generic function with 1 method)

f automatically has the derivatives defined via the tracing mechanism. It will do this by directly building the internals of your function and differentiating that.

However, often you may want to define your own derivatives so that way automatic Jacobian etc. calculations can utilize this information. This can allow for more succinct versions of the derivatives to be calculated to scale to larger systems. You can define derivatives for your function via the dispatch:

# `N` arguments are accepted by the relevant method of `my_function`
-Symbolics.derivative(::typeof(my_function), args::NTuple{N,Any}, ::Val{i})

where i means that it's the derivative with respect to the ith argument. args is the array of arguments, so, for example, if your function is f(x,t), then args = [x,t]. You should return an Term for the derivative of your function.

For example, sin(t)'s derivative (by t) is given by the following:

Symbolics.derivative(::typeof(sin), args::NTuple{1,Any}, ::Val{1}) = cos(args[1])
+Symbolics.derivative(::typeof(my_function), args::NTuple{N,Any}, ::Val{i})

where i means that it's the derivative with respect to the ith argument. args is the array of arguments, so, for example, if your function is f(x,t), then args = [x,t]. You should return an Term for the derivative of your function.

             threaded=false,
             thread_subtree_cutoff=100,

Simplify an expression (x) by applying rewriter until there are no changes. expand=true applies expand in the beginning of each fixpoint iteration.

By default, simplify will assume denominators are not zero and allow cancellation in fractions. Pass simplify_fractions=false to prevent this.

Registration API

Symbolics.@register_symbolic — Macro
@register_symbolic(expr, define_promotion = true, Ts = [Real])

Overload appropriate methods so that Symbolics can stop tracing into the registered function. If define_promotion is true, then a promotion method in the form of

SymbolicUtils.promote_symtype(::typeof(f_registered), args...) = Real # or the annotated return type

is defined for the register function. Note that when defining multiple register overloads for one function, all the rest of the registers must set define_promotion to false except for the first one, to avoid method overwriting.

Examples

@register_symbolic foo(x, y)
 @register_symbolic foo(x, y::Bool) false # do not overload a duplicate promotion rule
 @register_symbolic goo(x, y::Int) # `y` is not overloaded to take symbolic objects
-@register_symbolic hoo(x, y)::Int # `hoo` returns `Int`

See @register_array_symbolic to register functions which return arrays.

 @register_array_symbolic vandermonde(x::AbstractVector) begin
     size=(length(x), length(x))
     eltype=eltype(x) # optional, will default to the promoted eltypes of x
 end

You can also register calls on callable structs:

@register_array_symbolic (c::Conv)(x::AbstractMatrix) begin
     size=size(x) .- size(c.kernel) .+ 1
     eltype=promote_type(eltype(x), eltype(c))

Direct Registration API (Advanced, Experimental)

Warn

This is a lower level API which is not as stable as the macro APIs.

In some circumstances you may need to use the direct API in order to define registration on functions or types without using the macro. This is done by directly defining dispatches on symbolic objects.

A good example of this is DataInterpolations.jl's interpolations object. On an interpolation by a symbolic variable, we generate the symbolic function (the term) for the interpolation function. This looks like:

SymbolicUtils.promote_symtype(t::AbstractInterpolation, args...) = Real

Additionally a symbolic name is required:

Base.nameof(interp::AbstractInterpolation) = :Interpolation

The derivative is defined similarly to the macro case:

     Symbolics.unwrap(derivative(interp, Symbolics.wrap(args[1])))

Limitations

Symbolic-ness Tied to Environment Definitions

The parsing to a symbolic expression has to be able to recognize the difference between functions, numbers, and globals defined within one's Julia environment and those that are to be made symbolic. The way this functionality handles this problem is that it does not define anything as symbolic that is already defined in the chosen mod module. For example, f(x,y) will have f as non-symbolic if the function f (named f) is defined in mod, i.e. if isdefined(mod,:f) is true. When the symbol is defined, it will be replaced by its value. Notably, this means that the parsing behavior changes depending on the environment that it is applied.

For example:

parse_expr_to_symbolic(:(x - y),@__MODULE__) # x - y
 x = 2.0
-parse_expr_to_symbolic(:(x - y),@__MODULE__) # 2.0 - y

This is required to detect that standard functions like - are functions instead of symbolic symbols. For safety, one should create anonymous modules or other sub-environments to ensure no stray variables are defined.

Metadata is Blank

Because all the variables defined by the expressions are not defined with the standard @variables, there is no metadata that is or can be associated with any of the generated variables. Instead, they all have blank metadata, but are defined in the Real domain. Thus, the variables which come out of this parsing may not evaluate as equal to a symbolic variable defined elsewhere.

symbolic_solve only supports symbolic, i.e. non-floating point computations, and thus prefers equations where the coefficients are integer, rational, or symbolic. Floating point coefficients are transformed into rational values and BigInt values are used internally with a potential performance loss, and thus it is recommended that this functionality is only used with floating point values if necessary. In contrast, symbolic_linear_solve directly handles floating point values using standard factorizations.

More technical details and examples

Technical details

The symbolic_solve function uses 4 hidden solvers in order to solve the user's input. Its base, solve_univar, uses analytic solutions up to polynomials of degree 4 and factoring as its method for solving univariate polynomials. The function's solve_multipoly uses GCD on the input polynomials then throws passes the result to solve_univar. The function's solve_multivar uses Groebner basis and a separating form in order to create linear equations in the input variables and a single high degree equation in the separating variable [1]. Each equation resulting from the basis is then passed to solve_univar. We can see that essentially, solve_univar is the building block of symbolic_solve. If the input is not a valid polynomial and can not be solved by the algorithm above, symbolic_solve passes it to ia_solve, which attempts solving by attraction and isolation [2]. This only works when the input is a single expression and the user wants the answer in terms of a single variable. Say log(x) - a == 0 gives us [e^a].

Symbolics.solve_univar — Function
solve_univar(expression, x; dropmultiplicity=true)

This solver uses analytic solutions up to degree 4 to solve univariate polynomials. It first handles the special case of the expression being of operation ^. E.g. math (x+2)^{20}. We solve this by removing the int 20, then solving the poly math x+2 on its own. If the parameter mult of the solver is set to true, we then repeat the found roots of math x+2 twenty times before returning the results to the user.

Step 2 is filtering the expression after handling this special case, and then factoring it using factor_use_nemo. We then solve all the factors outputted using the analytic methods implemented in the function get_roots and its children.

Arguments

  • expr: Single symbolics Num or SymbolicUtils.BasicSymbolic expression. This is equated to 0 and then solved. E.g. expr = x+2, we solve x+2 = 0

  • x: Single symbolics variable

  • dropmultiplicity (optional): Print repeated roots or not?

Symbolics.ia_solve — Function
ia_solve(lhs, var; kwargs...)

This function attempts to solve transcendental functions by first checking the "smart" number of occurrences in the input LHS. By smart here we mean that polynomials are counted as 1 occurrence. for example x^2 + 2x is 1 occurrence of x. So we abstract all occurrences of x's as polynomials. Say: log(x+1) + x^2 is seen as log(f(x)) + g(x) so there are 2 occurrences of x. If there is only 1 occurrence of x in an input expression, isolate is called.

Isolate reverses all operations applied on the occurrence of x until we have f(x) = some constant then we can solve this using our polynomial solvers.

If more than 1 occurrence of x is found, ia_solve attempts to attract the occurrences of x in order to reduce these occurrences to 1. For example, log(x+1) + log(x-1) can be converted to log(x^2 - 1) which now could be isolated using Isolate.

attract(lhs, var) currently uses 4 techniques for attraction.

  • Log addition: log(f(x)) + log(g(x)) => log(h(x))
  • Exponential simplification: a*b^(f(x)) + c*d^(g(x)) => f(x) * log(b) - g(x) * log(d) + log(-a/c). And now this is actually 1 occurrence of x since f(x) and g(x) are just multiplied by constants not wrapped in some operation.
  • Trig simplification: this bruteforces multiple trig identities and doesn't detect them before hand.
  • Polynomialization: as a last resort, attract attempts to polynomialize the expression. Say sin(x+2)^2 + sin(x+2) + 10 is converted to X^2 + X + 10, we then solve this using our polynomial solver, and afterwards, isolate sin(x+2) = the roots found by solve for X^2 + X + 10

After attraction, we check the number of occurrences again, and if its 1, we isolate, if not, we throw an error to tell the user that this is currently unsolvable by our covered techniques.

Arguments

  • lhs: a Num/SymbolicUtils.BasicSymbolic
  • var: variable to solve for.

Keyword arguments

  • warns = true: Whether to emit warnings for unsolvable expressions.
  • complex_roots = true: Whether to consider complex roots of x ^ n ~ y, where n is an integer.
  • periodic_roots = true: If true, isolate f(x) ~ y as x ~ finv(y) + n * period where is_periodic(f) == true, finv = left_inverse(f) and period = fundamental_period(f). n is a new anonymous symbolic variable.

symbolic_solve only supports symbolic, i.e. non-floating point computations, and thus prefers equations where the coefficients are integer, rational, or symbolic. Floating point coefficients are transformed into rational values and BigInt values are used internally with a potential performance loss, and thus it is recommended that this functionality is only used with floating point values if necessary. In contrast, symbolic_linear_solve directly handles floating point values using standard factorizations.

More technical details and examples

Technical details

The symbolic_solve function uses 4 hidden solvers in order to solve the user's input. Its base, solve_univar, uses analytic solutions up to polynomials of degree 4 and factoring as its method for solving univariate polynomials. The function's solve_multipoly uses GCD on the input polynomials then throws passes the result to solve_univar. The function's solve_multivar uses Groebner basis and a separating form in order to create linear equations in the input variables and a single high degree equation in the separating variable [1]. Each equation resulting from the basis is then passed to solve_univar. We can see that essentially, solve_univar is the building block of symbolic_solve. If the input is not a valid polynomial and can not be solved by the algorithm above, symbolic_solve passes it to ia_solve, which attempts solving by attraction and isolation [2]. This only works when the input is a single expression and the user wants the answer in terms of a single variable. Say log(x) - a == 0 gives us [e^a].

Symbolics.ia_conditions! — Function
ia_conditions!(f, lhs, rhs::Vector{Any}, conditions::Vector{Tuple})

If f is a left-invertible function, lhs and rhs[i] are univariate functions and f(lhs) ~ rhs[i] for all i in eachindex(rhss), push to conditions all the relevant conditions on lhs or rhs[i]. Each condition is of the form (sym, op) where sym is an expression involving lhs and/or rhs[i] and op is a binary relational operator. The condition op(sym, 0) is then required to be true for the equation f(lhs) ~ rhs[i] to be valid.

For example, if f = log, lhs = x and rhss = [y, z] then the condition x > 0 must be true. Thus, (lhs, >) is pushed to conditions. Similarly, if f = sqrt, rhs[i] >= 0 must be true for all i, and so (y, >=) and (z, >=) will be appended to conditions.

A note about functions restricted to Numbers

Sym and Term objects are NOT subtypes of Number. Symbolics provides a simple wrapper type called Num which is a subtype of Real. Num wraps either a Sym or a Term or any other object, defines the same set of operations as symbolic expressions and forwards those to the values it wraps. You can use Symbolics.value function to unwrap a Num.

By default, the @variables macros return Num-wrapped objects to allow calling functions which are restricted to Number or Real.

The output, here the in-place modified du, is a symbolic representation of each output of the function. We can then utilize this in the Symbolics functionality. For example, let's build a parallel version of f first:

fastf = eval(Symbolics.build_function(du,u,
             parallel=Symbolics.MultithreadedForm())[2])
#13 (generic function with 1 method)

Now let's compute the sparse Jacobian function and compile a fast multithreaded version:

jac = Symbolics.sparsejacobian(vec(du), vec(u))
 row,col,val = findnz(jac)
-scatter(row,col,legend=false,ms=1,c=:black)
Example block output
fjac = eval(Symbolics.build_function(jac,u,
+scatter(row,col,legend=false,ms=1,c=:black)

fjac = eval(Symbolics.build_function(jac,u,
             parallel=Symbolics.MultithreadedForm())[2])
#15 (generic function with 1 method)

It takes awhile for this to generate, but the results will be worth it! Now let's set up the parabolic PDE to be solved by DifferentialEquations.jl. We will set up the vanilla version and the sparse multithreaded version:

This looks very different from our first series E_pert. If they are the same, we should get $0$ if we subtract and expand both as multivariate Taylor series in $(e,M)$. Indeed:
