摘要:

本文提出了一种求解旅行商问题的新策略,这是一个著名的组合优化问题。特别是,我们考虑了模仿学习框架,它有助于确定性算法在需要时做出正确的选择,从而在保持解决方案的准确性的同时加快速度,而不会受到不可预测性和潜在的大偏差的影响。此外,我们证明了一个强大的泛化能力的图神经网络下训练的模仿学习框架。具体来说,该模型能够比基线更快地解决大型TSP实例,而在训练时只看到小型TSP实例。

英文摘要:

In this paper, we provide a novel strategy for solving Traveling Salesman Problem, which is a famous combinatorial optimization problem studied intensely in the TCS community. In particular, we consider the imitation learning framework, which helps a deterministic algorithm making good choices whenever it needs to, resulting in a speed up while maintaining the exactness of the solution without suffering from the unpredictability and a potential large deviation. Furthermore, we demonstrate a strong generalization ability of a graph neural network trained under the imitation learning framework. Specifically, the model is capable of solving a large instance of TSP faster than the baseline while has only seen small TSP instances when training.
