Fine-Grain GPU Parallelization of the Generalized Partition Crossover for Large-Scale Traveling Salesman Problems
Researchers have developed a new way to speed up the solution of large-scale Traveling Salesman Problems using Graphics Processing Units (GPUs). They achieved this by reformulating the Generalized Partition Crossover operator as a graph-parallel problem and implementing it on CUDA, a parallel computing platform. The results show that their approach can solve larger instances with significant acceleration, reducing memory overhead in the process.
