BehaviorSearch is a handy and simple-to-use tool; however, the GitHub page shows little movement (the most recent commit was two years ago). The last thing I know is that a Multi-Objective optimization was in development (5 years ago), with no updates regarding that new version.
A better-optimized (for multi-threading and multi-core) BehaviorSearch with MOEA is the feature I expect the most.
Thank you for this feedback! BehaviorSearch has not been abandoned, but it is true that we haven’t done much with it in a few years. We have a small development team and can only focus on a few things at a time. If you are a developer and you have the time and interest to contribute, we can help you get set up to develop those features. If not, we will keep your request in mind as we prioritize future development.
