learning combinatorial optimization algorithms over graphs

Bibliographic details on Learning Combinatorial Optimization Algorithms over Graphs. 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. While deep learning has proven enormously successful at a range of tasks, an expanding area of interest concerns systems that can flexibly combine learning with optimization. Today, combinatorial optimization algorithms developed in the OR community form the backbone of the most important modern industries including transportation, logistics, scheduling, finance and supply chains. Nonetheless, there exists a broad range of exact combinatorial optimization algorithms, which are guaranteed to find an optimal solution despite a worst-case exponential time complexity [52]. 1.

Combinatorial optimization is a subfield of mathematical optimization that is related to operations research, algorithm theory, and computational complexity theory.It has important applications in several fields, including artificial intelligence, machine learning, auction theory, software engineering, applied mathematics and theoretical computer science. We show that our framework can be applied to a diverse … optimization algorithms together with machine learning. each edge has at least one end in ! NeurIPS, 2017. Very recently, an important step was taken towards real-world sized problem with the paper “Learning Heuristics Over Large Graphs Via Deep Reinforcement Learning”. College of Computing, Georgia Institute of Technology. Interestingly, the approach transfers well to different data distributions, larger instances and other problems. Combinatorial optimization problems over graphs have attracted interests from the theory and algorithm design communities over the years, due to the practical need from numerous application areas, such as routing, scheduling, assignment and social networks. 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.

Combinatorial algorithms over graphs . Part of: Advances in Neural Information Processing Systems 30 (NIPS 2017) [Supplemental] Authors. Combinatorial optimization algorithms for graph problems are usually designed afresh for each new problem with careful attention by an expert to the problem structure. We consider two optimization tasks for computation graphs: minimizing running time and peak memory usage. (2017) - aurelienbibaut/DQN_MVC The remainder of this paperis organized as follows. Similarly, (Khalil et al., 2017) solved optimization problems over graphs using graph embedding and deep Q-learning (DQN) algorithms (Mnih et al., 2015). The authors propose a reinforcement learning strategy to learn new heuristic (specifically, greedy) strategies for solving graph-based combinatorial problems.

In comparison to an extensive set of baselines, our approach achieves significant improvements over classical and other learning-based methods on these two tasks.
