Abstract

In certain complex environments, learning tends to be unstable, so to mitigate this issue, we propose Strict Subgoal Execution (SSE). SSE is a graph-based Hierarchical Reinforcement Learning framework. Currently, there are few studies addressing this specific challenge, but SSE provides a stable approach by combining Goal-Conditioned Reinforcement Learning with structured subgoal planning.
