This paper presents a framework to tackle combinatorial optimization problems using neural networks and reinforcement learning. In the Neural Combinatorial Optimization (NCO) framework, a heuristic is parameterized using a neural network to obtain solutions for many different combinatorial optimization problems without hand-engineering. Bibliographic details on Neural Combinatorial Optimization with Reinforcement Learning. As demonstrated in [ 5], Reinforcement Learning (RL) can be used to that achieve that goal. This paper presents a framework to tackle combinatorial optimization problems using neural networks and reinforcement learning. By contrast, we believe Reinforcement Learning (RL) provides an appropriate paradigm for training neural networks for combinatorial optimization, especially because these problems have relatively simple reward mechanisms that could be even used at test time. , Reinforcement Learning (RL) can be used to that achieve that goal.

We focus on the traveling salesman problem (TSP) and train a recurrent network that, given a set of city coordinates, predicts a distribution over different city permutations. (2016)[2], as a framework to tackle combinatorial optimization problems using Reinforcement Learning. Linear and mixed-integer linear programming problems are the workhorse of combinatorial optimization because they can model a wide variety of problems and are the best understood, i.e., there are reliable algorithms and software tools to solve them.We give them special considerations in this paper but, of course, they do not represent the entire combinatorial optimization… Recent progress in reinforcement learning (RL) using self-play has shown remarkable performance with several board games (e.g., Chess and Go) and video games (e.g., Atari games and Dota2). and a rule-picking component, each parameterized by a neural network trained with actor-critic methods in reinforcement learning. I have implemented the basic RL pretraining model with greedy decoding from the paper. We focus on the traveling salesman problem (TSP) and train a recurrent neural network that, given a set of city \mbox {coordinates}, predicts a distribution over different city … The recent years have witnessed the rapid expansion of the frontier of using machine learning to solve the combinatorial optimization problems, and the related technologies vary from deep neural networks, reinforcement learning to decision tree models, especially given large amount of training data. Machine learning, 8(3-4):229–256, 1992. Combinatorial optimization problems over graphs arising from numerous application domains, such as social networks, transportation, telecommunications and scheduling, are NP-hard, and have thus attracted considerable interest from the theory and algorithm design communities over the years. every innovation in technology and every invention that improved our lives and our ability to survive and thrive on earth This technique is Reinforcement Learning (RL), and can be used to tackle combinatorial optimization problems.
