Multimode extensions of Combinatorial Optimization problems [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2016
We review some complexity results and present a viable heuristic approach based on the Variable Neighborhood Search (VNS) framework for multimode extension of combinatorial optimization problems, such as the the Set Covering Problem (SCP) and the Covering Location Problem (CLP).

DeepACO: Neural-enhanced Ant Systems for Combinatorial Optimization [PDF]

open access: yesNeural Information Processing Systems, 2023
Ant Colony Optimization (ACO) is a meta-heuristic algorithm that has been successfully applied to various Combinatorial Optimization Problems (COPs). Traditionally, customizing ACO for a specific problem requires the expert design of knowledge-driven ...

Combinatorial optimization and reasoning with graph neural networks [PDF]

open access: yesInternational Joint Conference on Artificial Intelligence, 2021
Combinatorial optimization is a well-established area in operations research and computer science. Until recently, its methods have mostly focused on solving problem instances in isolation, ignoring the fact that they often stem from related data ...

Hysteresis in Combinatorial Optimization Problems

open access: yesThe International FLAIRS Conference Proceedings, 2021
Hysteresis is a physical phenomenon reflected in macroscopic observables of materials that are subjected to external perturbations. For example, magnetic hysteresis is observed in ferromagnetic metals such as iron, nickel and cobalt in the presence of a changing external magnetic field.

Sym-NCO: Leveraging Symmetricity for Neural Combinatorial Optimization [PDF]

open access: yesNeural Information Processing Systems, 2022
Deep reinforcement learning (DRL)-based combinatorial optimization (CO) methods (i.e., DRL-NCO) have shown significant merit over the conventional CO solvers as DRL-NCO is capable of learning CO solvers less relying on problem-specific expert domain ...

DIMES: A Differentiable Meta Solver for Combinatorial Optimization Problems [PDF]

open access: yesNeural Information Processing Systems, 2022
Recently, deep reinforcement learning (DRL) models have shown promising results in solving NP-hard Combinatorial Optimization (CO) problems. However, most DRL solvers can only scale to a few hundreds of nodes for combinatorial optimization problems on ...
