# reinforcement learning for combinatorial optimization: a survey

Several heuristics have been proposed for the OPTW, yet in comparison with machine learning models, a heuristic typically has a smaller potential for generalization and personalization.

A neural network allows learning solutions using reinforcement learning or in a supervised way, depending on the available data. 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. In this section, we survey how the learned policies (whether from demonstration or experience) are combined with traditional combinatorial optimization algorithms, i.e., considering machine learning and explicit algorithms as building blocks, we survey how they can be laid out in different templates. This survey explores the synergy between CO and reinforcement learning (RL) framework, which can become a promising direction for solving combinatorial problems. arXiv:1811.09083, 2018. endobj << /Type /XObject /Subtype /Form /BBox [ 0 0 100 100 ] Finally, the effectiveness of the proposed algorithm is demonstrated by numerical simulation. /Matrix [ 1 0 0 1 0 0 ] /Resources 8 0 R >> x���P(�� ��endstream learning. self-play for hierarchical reinforcement learning. stream endobj Ioannis One area where very large MDPs arise is in complex optimization problems. x���P(�� ��endstream stream Abstract: Combinatorial optimization (CO) is the workhorse of numerous important applications in operations research, engineering and other fields and, thus, has been attracting enormous attention from the research community for over a century. training for image captioning.

We train the Pointer Network with the TTDP problem in mind, by sampling variables that can change across tourists for a particular instance-region: starting position, starting time, time available and the scores of each point of interest. The practical side of theoretical computer science, such as computational complexity, then needs to be addressed. We evaluate our approach on several existing benchmark OPTW instances. After a model-region is trained it can infer a solution for a particular tourist using beam search. Mehdi Mirza, Alex Graves, Timothy P. Lillicrap, Tim Harley, In AAAI, 2019.

We first formulate the problem as an NP-hard combinatorial optimization problem, then reformulate it as a non-cooperative game by applying the penalty function method. With such tasks often NP-hard and analytically intractable, reinforcement learning (RL) has shown promise as a framework with which efficient heuristic methods to tackle these problems can be learned. For that purpose, a n agent must be able to match each sequence of packets (e.g. Some efficient approaches to common problems involve using hand-crafted heuristics to sequentially construct a solution. /Matrix [ 1 0 0 1 0 0 ] /Resources 18 0 R >> Title: A Survey on Reinforcement Learning for Combinatorial Optimization.

Reinforcement learning stream Today, despite some efforts, most real-life combinatorial optimization problems remain out of the reach of reinforcement, The Orienteering Problem with Time Windows (OPTW) is a combinatorial optimization problem where the goal is to maximize the total scores collected from visited locations, under some time constraints. Broadly speaking, combinatorial optimization problems are problems that involve finding the âbestâ object from a finite set of objects. The learned policy behaves like a meta-algorithm that incrementally constructs a solution, with the action being determined by a graph [Schulman et al., 2017] John Schulman, Filip Wolski, Prafulla /Matrix [ 1 0 0 1 0 0 ] /Resources 27 0 R >> stream Preprints and early-stage research may not have been peer reviewed yet.

Therefore, it is intriguing to see how a combinatorial optimization problem can be formulated as a sequential decision making process and whether efficient heuristics can be implicitly learned by a reinforcement learning agent to find a solution. We show that it is able to generalize across different generated tourists for each region and that it generally outperforms the most commonly used heuristic while computing the solution in realistic times. Many efficient solutions to common problems involve using hand-crafted heuristics to sequentially construct a solution. To solve the game, a novel reinforcement learning approach based on Bi-directional LSTM neural network is proposed, which enables small base stations (SBSs) to predict a sequence of future actions over the next prediction window based on the historical network information.
