摘要:

本文评估了随机计算模拟退火(SC-SA)在求解大规模组合优化问题中的性能。SC-SA利用随机计算技术,通过随机位流实现计算,从而快速收敛到问题的全局最小能量。所提出的SC-SA在MAX-CUT问题(如Gset基准测试集)上与典型SA和现有模拟退火处理器进行了比较。仿真结果表明,SC-SA比传统SA快几个数量级。此外,SC-SA在K2000完全2000节点优化问题上实现了优于其他现有方法的MAX-CUT得分。

英文摘要:

In this paper, we evaluate stochastic-computing simulated annealing (SC-SA) for solving large-scale combinatorial optimization problems. SC-SA is designed using stochastic computing, where the computatoin is reazlied using random bitstream, resulting in fast converging to the global minimum energy of the problems. The proposed SC-SA is compared with a typical SA and existing simulated-annealing (SA) processors on the maximum cut (MAX-CUT) problems, such as Gset that is a benchmark for SA. The simulation results show that SC-SA realizes a few orders of magnitude faster than a typical SA. In addition, SC-SA achieves better MAX-CUT scores than other existing methods on K2000 that is a complete 2000-node optimization problem.
