Large Neighborhood Search based on Neural Construction Heuristics
, 2022 We propose a Large Neighborhood Search (LNS) approach utilizing a learned construction heuristic based on neural networks as repair operator to solve the vehicle routing problem with time windows (VRPTW). Our method uses graph neural networks to encode the problem and auto-regressively decodes a solution and is trained with reinforcement learning on ...

Very Large-Scale Neighborhood Search for the Quadratic Assignment Problem [PDF]
SSRN Electronic Journal, 2002 The quadratic assignment problem (QAP) consists of assigning n facilities to n locations to minimize the total weighted cost of interactions between facilities. The QAP arises in many diverse settings, is known to be NP-hard, and can be solved to optimality only for fairly small instances (typically, n ≤ 30).
