WebIn this paper, we propose a unique combination of reinforcement learning and graph embedding to address this challenge. The learned greedy policy behaves like a meta-algorithm that incrementally constructs a solution, and the action is determined by the output of a graph embedding network capturing the current state of the solution. WebWhen solving the graph coloring problem with a mathematical optimization solver, to avoid some symmetry in the solution space, it is recommended to add the following constraints. y k ≥ y k + 1 k = 1, …, K max − 1. Adding the above constraint forces to use preferentially color classes with low subscripts.
