VBON: A Relational Action-Graph Network for Mitigating Path Fixation in Sparse-Reward Reinforcement Learning.

Deep Reinforcement Learning (DRL) is often hindered by significant exploration challenges in dynamic environments with sparse rewards. A critical failure mode in such settings is Path Fixation, where the agent prematurely converges to the first discovered yet suboptimal solution trajectory. This convergence limited fur...
