Right now I only want to tune-up two parameters but the number of parameters might eventually grow so I would like to use a technique that can do high-dimensional gradient searches. optimparallel - A parallel version of scipy.optimize.minimize(method='L-BFGS-B') Using optimparallel.minimize_parallel() can significantly reduce the optimization time. For an objective function with an execution time of more than 0.1 seconds and p parameters the optimization speed increases by up to factor 1+p when no analytic gradient is specified and 1+p processor cores with sufficient A simple wrapper for scipy.optimize.minimize using JAX. Args: fun: The objective function to be minimized, written in JAX code: so that it is automatically differentiable.

def … The documentation tries to explain how the args tuple is used Effectively, scipy.optimize.minimize will pass whatever is in args as the remainder of the arguments to fun, using the asterisk arguments notation: the function is then called as fun(x, *args) during optimization. options: dict, optional The scipy.optimize.minimize options. verbose : boolean, optional If True, informations are displayed in the shell. Returns ----- out : scipy.optimize.minimize solution object The solution of the minimization algorithm.
