Send me your difficult computational requirements, your NP-complete problems, your befuddled designs. Really!
In recent years, one of the projects on which I've spent a good deal of time is the Darwin java framework for evolutionary computation (http://sourceforge.net/projects/darwin/). It's designed to make it relatively easy for a developer to set up, execute and refine a genetic algorithm or program. I need examples. But I also need (paying) contracts. I need to use it to do solve some real-world problems. I'm also looking for (volunteer) developers... and for people to comment on it and maybe offer constructive criticism.
Darwin is a framework which models the basics of genetic algorithms using a set of interfaces, (extensible) abstract classes and default concrete implementations. Objects with a long lifecycle (the beans) are configured using XML files (provides dependency injection). Other short-lived objects are created as needed using factory classes. Darwin runs a simple genetic simulation out of the box
