I need a solver of stiff Inital-Value Problems (IVP) in python exploiting RK4 preferably explicit. I have been searching for past few days but could not find it. Following are my queries:
- Does the solver, i.e. any module, exist?
- If no, will it be reasonable to code one? I am asking this because I can't find any reference for using RK4-explicit for stiff problems.
