We focus on combinatorial optimization problems and in-troduce a general framework for decision-focused learning, where the machine learning model is directly trained in con-junction with the optimization algorithm to produce high- The learned greedy policy behaves like a meta-algorithm that incrementally constructs a solution, and the action is determined by the output of a graph embedding network capturing the current state of the solution. More specifically, we extend the neural combinatorial optimization framework to solve the traveling salesman problem (TSP). College of Computing, Georgia Institute of Technology. However, graph representation techniques---that convert graphs to real-valued vectors for use with neural networks---are still in their infancy. A further argument for using graphs for characterizing learning problems was found in the connection it makes to the literature on network flow algorithms and other deep results of combinatorial optimization problems. 4080-4115, 2013.

The learned greedy policy behaves like a meta-algorithm that incrementally constructs a solution, and the action is determined by the output of a graph embedding network capturing the current state of the solution. The aim of the study is to provide interesting insights on how efficient machine learning algorithms could be adapted to solve combinatorial optimization problems in conjunction with existing heuristic procedures. In comparison to an extensive set of baselines, our approach achieves significant improvements over classical and other learning-based methods on these two tasks. Comput. View Profile, Elias B. Khalil. Annals of Probability, Vol. Advances in Neural Information Processing Systems (2017), pp. Our approach combines deep learning techniques with useful algorithmic elements from classic heuristics. In this paper, we propose a unique combination of reinforcement learning and graph embedding to address this challenge. A specially designed neural MCTS algorithm is then introduced to train Zermelo game agents.

Khalil, Yuyu Zhang, Bistra Dilkina, Le Song (Submitted on 5 Apr 2017 , revised 12 Sep 2017 (this version, v3), latest version 21 Feb 2018 ) Abstract: The design of good heuristics or approximation algorithms for NP … Mathematical Biosciences and Engineering, 2020, 17(2): 975-997. doi: 10.3934/mbe.2020052 . This algorithm has better performance compared to others such as genetic algorithm in terms of speed, memory consumption and accuracy of solutions. In many real-world applications, it is typically the case that the same optimization problem is solved again and again on a regular basis, maintaining the same problem structure but differing in the data. Can we automate this challenging, tedious process, and learn the algorithms instead?.. We test this algorithm on a variety of optimization problems. It can explore unknown parts of search space well.
