 ## Compiler Architecture Overview
 
-In general, Feynman diagrams represents high-order integral. The integrand are propagators/interactions composed by the basis arithmetic operations (multiplication, addition). The sequence of calculating the integrand by combining the propagators/interactions with the arithmetic operatos can be represented as an algebraic computational graph. In this sense, the computational graph serves as an intermediate representation that standardizes the treatment of various diagram types, ensuring a consistent approach across different QFT calculations.
