Attention, Learn to Solve Routing Problems! (ICLR 2019) 原文链接:https://arxiv.org/pdf/1803.0847 这篇文章基于Transformer模型提出了一个基于注意力层的模型,并采用REINFORCE方法训练模型,来求解以下几种组合优化问题: 旅行商问题(Travelling Salesman Problem, TSP)...
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...
Attention, learn to solve routing problems!Wouter KoolHerke van HoofMax WellingOpenReviewInternational Conference on Learning Representations
The attention model consists of an encoder and a decoder. The encoder is used to learn the representation of each node and the graph. The decoder is used to predict the routing.Remarks: the graph structure seems only to be used to calculate the compatibility between different nodes...
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...
With the same hyperparameters, we learn strong heuristics for two variants of the Vehicle Routing Problem (VRP), the Orienteering Problem (OP) and (a stochastic variant of) the Prize Collecting TSP (PCTSP), outperforming a wide range of baselines and getting results close to highly optimized ...
