[NeurIPS 2023] DeepACO: Neural-enhanced Ant Systems for Combinatorial Optimization

🥳 Welcome! This codebase accompanies the paper DeepACO: Neural-enhanced Ant Systems for Combinatorial Optimization.

🚀 Introduction

DeepACO is a generic framework that leverages deep reinforcement learning to automate heuristic designs. It serves to strengthen the heuristic measures of existing ACO algorithms and dispense with laborious manual design in future ACO applications.
