Version [2.0.0] - [DetPy (Differential evolution tools): A python toolbox for solving optimization problems using differential evolution]

This article presents version 2.0 of the DetPy (Differential Evolution Tools) library, a Python toolbox for solving advanced optimization problems using differential evolution and its variants. The updated version introduces 15 additional algorithms, increasing the total number of available methods to 30 and enabling extensive experimental studies in differential evolution. Version 2.0 implements a flexible stopping mechanism, where the number of objective function evaluations (NFE) serves as the default termination criterion, while users may define custom stopping conditions. The update also includes minor bug fixes, code refactoring, and improvements that enhance software robustness and maintainability.
