GOFit

Global Optimization for Fitting problems

Release: 1.0.0

Date: 10 September 2025

Author: Jaroslav Fowkes

GOFit is a package of C++ algorithms with python interfaces designed for the global optimization of parameters in curve fitting, i.e. for nonlinear least-squares problems arising from curve fitting. GOFit was developed with scientific curve fitting problems in mind [1] but is also applicable to general curve fitting problems provided they can be formulated as nonlinear least-squares problems.
