Optimization of multimodal functions is hard for traditional optimization techniques. Holland's genetic algorithm combined with the concept of niche and speciation already showed success in such difficult problems. Some implementations of this concept exist, but the effective ones all lack…

This thesis presents three trie organizations for various binary tries. The new trie structures have two distinctive features: (1) they store no pointers and require two bits per node in the worst case, and (2) they partition tries into pages…
