We focus on the traveling salesman problem Learning to Perform Local Rewriting for Combinatorial Optimization Xinyun Chen UC Berkeley xinyun.chen@berkeley.edu Yuandong Tian Facebook AI Research yuandong@fb.com Abstract Search-based methods for hard combinatorial optimization are often guided by heuristics. We empirically demonstrate that, even when using optimal solutions as labeled data to optimize a supervised mapping, the generalization is rather poor compared to an RL agent that explores different tours and observes their corresponding rewards. ```, python main.py --maxlength=20 --inferencemode=True --restoremodel=True --restorefrom=20/model Combinatorial optimization problems are typically tackled by the branch-and-bound paradigm.

Despite the computational expense, without much to the KnapSack, another NP-hard problem, the same method obtains optimal Need a bug fixed? , Reinforcement Learning (RL) can be used to that achieve that goal. If you believe there is structure in your combinatorial problem, however, a carefully crafted neural network trained on "self play" (exploring select branches of the tree to the leaves) might give you probability distributions over which branches of the search tree are most promising. Corpus ID: 49566564. Quoc V.
