This module contains everything related to minimization in zfit.

Minimizers#

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.
