PyDDE is an open source numerical solver for systems of delay differential equations (DDEs),
implemented as a Python package and written in both Python and C. It is built around the numerical
routines of the R package ddesolve, which is itself based on Simon Wood's Solv95, a DDE solver for
Microsoft Windows systems written in C.
PyDDE can solve a wide range of ODE and DDE models with discontinuities that may have state-
dependent effects but state-independent timings. Simulation is handled by an adaptively-stepping
embedded RK2(3) scheme with cubic Hermite interpolation for calculation of delay terms. Some of ...
