large delay systems

[richfitz]

Alternative approaches:

• http://www.unige.ch/~hairer/software.html (an actual DDE solver)
• sundials (requires storing the previous points in the user data), see also: Delay differential equation with constant delay sys-bio/roadrunner#303 and http://sundials.2283335.n4.nabble.com/Implementing-ODE-s-with-delay-td3240846.html
• odeint (also requires some faff with previous points)
• http://www.radford.edu/~thompson/ffddes/
• https://cran.r-project.org/web/packages/PBSddesolve/index.html -- see http://web.archive.org/web/20121112063021/http://www.maths.bath.ac.uk/~sw283/simon/dde.html as the R package does not allow for compiled target functions, but could probably be modified to support this.

Moar:

• http://www.netlib.org/ode/ddverk.f
• the radar solver on the Hairer page (has a bespoke and impossible to work with licence)

• http://www.cs.toronto.edu/~hzp/index_files/ddverk90/hz-thesis.pdf -- implementation is here: http://www.cs.toronto.edu/~hzp/index_files/software.html -- but no licence information

retard is open licenced www.unige.ch/~hairer/software.html (See note at top of page)

dklag6 is a Fortran 77 precusor to dde_solver http://www.radford.edu/~thompson/misc/dklag.html but has no explicit licence (dde_solver is open I believe)

I've implemented dopri5, plus simple delay support in dde
