well, this one is gonna be easy for you :) yes, I am the sole author. Everything from design to implementation is mine.
The JGraphT library was supposed to be used for a grammar where Individual strings would represent graphs. The implementation is incomplete and we can easily replace JGraphT with some other graph library. There are many opportunities for parallelization. One way could be creating relatively isolated pools of populations with limited inter-pool exchange of best individuals. This would give evolution a chance to explore various paths. Another is somehow parallelizing evaluation of individuals in accordance with the fitness function. As someone mentioned it is probably the costliest part of the evolution process. Frankly I have to think more about it. But I am sure we can leverage the power of multiple machines to make the process much faster and at the same time explore more of the solution space. I have some experience with parallel programming from my post-grad days.
