Parallelizing Combinatorial Optimization Heuristics with GPUs

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 6, Page # 265–280, 2018; DOI: 10.25046/aj030635
Abstract:

Combinatorial optimization problems are often NP-hard and too complex to be solved within a reasonable time frame by exact methods. Heuristic methods which do not offer a convergence guarantee could obtain some satisfactory resolution for combinatorial optimization problems. However, it is not only very time consuming for Central Processing Units (CPU) but also very difficult…
