Kolla 和 Tulsiani [KT07、Kol11] 以及 Arora、Barak 和 Steurer [ABS10] 介绍了子空间枚举技术,该技术给出了图问题的近似算法,例如独特博弈和小集扩展;此类算法的运行时间在图的阈值秩中呈指数增长。
Kolla and Tulsiani [KT07, Kol11] and Arora, Barak and Steurer [ABS10] introduced the technique of subspace enumeration, which gives approximation algorithms for graph problems such as unique games and small set expansion; the running time of such algorithms is exponential in the threshold-rank of the graph.
