Minimize

This module contains everything related to minimization in zfit.

zfit supplies wrappers for different minimizers from multiple libraries. Most of the are local minimizers (such as Minuit, IpyoptV1 or ScipyLBFGSBV1 are) while there are also a few global ones such as the NLoptISRESV1 or NLoptStoGOV1.
