先行研究と比べてどこがすごい?

他の組合せ最適化問題にも応用可能か?

Heuristics are typically expressed in the form of rules, which can be interpreted as policies to make decisions. We believe that these policies can be parameterized using DNNs, and be trained to obtain new and stronger algorithms for many different combinatorial optimization problems, similar to the way DNNs have boosted performance in the applications mentioned before.

ヒューリスティクスは決定を行うルールの集合と考えることができるので、DNNsでパラメタライズし学習することでより強力なアルゴリズムを獲得できるはず。

計算量

computing a single instance for TSP100 takes 0.03s on a 6850K CPU, whereas we solve 10000 instances using a single 1080Ti in 5s (0.0005s/instance). Our method is O(n 2 ), and given sufficient parallelism runs in O(n),
