The MOEA Framework is a Java library for developing and experimenting with multiobjective evolutionary algorithms (MOEAs) and other general-purpose optimization algorithms and metaheuristics. A number of algorithms are provided out-of-the-box, including NSGA-II, ε-MOEA, GDE3, and MOEA/D.
PyDSM is a Python Delta Sigma Modulator toolbox. It contains tools for experimenting with ΔΣ modulators. It focuses mostly on experimentation with different techniques for the design of the modulator Noise Transfer Function (NTF) and simulation of a generic digital modulator.
