I have a large amount of one-dimensional nonlinear fixed point problems to solve, what is the most efficient numerical solver? I'm currently using scipy.optimize.fixed_point, it takes around 17s to run 1000 of my tasks. Thanks for any suggestions.
Fastest way to compute large amount of fixed points in python?

If these are all 1D, you can take the fixed_point source, https://github.com/scipy/scipy/blob/v1.5.2/scipy/optimize/minpack.py#L876 simplify it (can decide once on the acceleration strategy, no need for _lazywhere etc) and compile it with either cython or numba.
