smoof (version 1.5.1)

Single and Multi-Objective Optimization Test Functions

Description

Provides generators for a high number of both single- and multi- objective test functions which are frequently used for the benchmarking of (numerical) optimization algorithms. Moreover, it offers a set of convenient functions to generate, plot and work with objective functions.
