After several years of development, I share with you Metaheuristics.jl This package implements state-of-the-art metaheuristic algorithms for single and multi-objective optimization. The aim of this package is to provide easy to use (and fast) metaheuristics for numerical global optimization. Metah…

Congratulations on the package! I see you have some constraint handling in some of the algorithms. I think this might be the first Julia package for metaheuristics that can handle equality and inequality constraints natively. Would be great to create a wrapper for Metaheuristics in Nonconvex.jl .

Thanks for your comment. Good suggestion!

Looks like a great package! Very often I need to optimize expensive black-box functions, and having an optimizer that offers multi-threaded, simultaneous evaluation of multiple candidate solutions significantly reduces execution time. Please consider adding this option to your population-based opt…

That is a great suggestion. The evaluation of multiple solutions will be included in future versions.

Parallel evaluation is available since v3.2.x (released mid-2022). BTW, v3.3 is coming with some new features: New features coming in next release opened 08:44PM - 12 Apr 23 UTC (UTC) [jmejia8] …

Say, I am only an occasional user to this interesting package. After working fine earlier, now it seems that it does not regocnize ‘BitArraySpace’ UndefVarError: `BitArraySpace` not defined I have tried Metaheuristics.BitArraySpace, etc and looked all over, but cannot figure out why the same cod…

Hi! Thank you for the package - it is absolutely great. I have just one question: How does Metaheuristics.jl “penalize” the objective function for not satisfying the constraints? From what I gather, it doesn’t use penalty method. Does it use something along the lines f^{\prime}(x) = f(x) (1 + \sum…

Good question. Looking at the list of algorithms Algorithms · Metaheuristics.jl , I would say that the question shouldn’t be asked at the higher level of Metaheuristics.jl, but at the lower level of each algo, since some of them don’t support constraint. Looking at the classical DE algo, I see no d…
