Weblem. In a graph G= (V;E) an independent set is a subset I V of vertices such that there is no edge (u;v) 2Ehaving both endpoints uand vcontained in I. In the maximum independent … 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.
