摘要

In this thesis, a genetic algorithm is employed to solve the Traveling Salesman Problem by utilizing reconfigurable hardware's speed, regular structure, and ability to quickly modify design elements to overcome unacceptable delays found in software optimizations. These delays are a result of the genetic algorithm's complexity. This thesis expands upon previous hardware implementations, adapting them to today's reconfigurable hardware. Exploiting the fine grain parallelization capabilities of hardware in specific areas of the algorithm is shown to provide decreased execution time. Allowing multiple simultaneously running genetic algorithms to communicate with each other's subpopulation through a migration operator exploits the hardware's coarse grain parallelization capabilities resulting in more accurate solutions. These parallelization techniques, however, add to resource costs and their tradeoffs and benefits are evaluated to determine the feasibility of these parallelization techniques.
