    Toward fast belief propagation for distributed constraint optimization problems via heuristic search

    Belief propagation (BP) approaches, such as Max-sum and its variants, are important methods to solve large-scale Distributed Constraint Optimization Problems. However, these algorithms face a huge challenge si...

    Learning heuristics for weighted CSPs through deep reinforcement learning

    Weighted constraint satisfaction problems (WCSPs) are one of the most important constraint programming models aiming to find a cost-minimal solution. Due to its NP-hardness, solving a WCSP usually requires eff...
