第一个贡献是提出了一个基于attention layers的模型 使用了基于确定性greedy rollout baseline的REINFORCE对模型进行了训练 作者使用上述模型对TSP,VRP,OP,PCTSP问题进行了测试TODO:主要理解TSP,VRP中模型的使用 Attention Model (PS:此部分先介绍就TSP而言的Attention model,对于CARP问题,模型相同,但input,mask和decoder ...
车辆路径问题(Vehicle Routing Problem, VRP), 车辆路线问题最早是由Dantzig和Ramser于1959年首次提出,它是指一定数量的客户,各自有不同数量的货物需求,配送中心向客户提供货物,由一个车队负责分送货物,组织适当的行车路线,目标是使得客户的需求得到满足,并能在一定的约束下,达到诸如路程最短、成本最小、耗费时间最少...
The value of the proposed method is not to outperform existing human-designed heuristics on specific tasks, but to scale to different routing problems with high flexibility.The attention model consists of an encoder and a decoder. The encoder is used to learn the representation of each...

The value of the proposed method is not to outperform existing human-designed heuristics on specific tasks, but to scale to different routing problems with high flexibility. This is important progress towards the situation where we can learn strong heuristics to solve a wide range of different prac...
