Researchers have introduced REVERSAL-BENCH, a new benchmark designed to measure the limitations of reset-free reinforcement learning agents in environments with irreversible actions. The benchmark controls the degree of reversibility and includes a reset oracle to verify state recoverability across various physics engines and manipulation tasks. Evaluations revealed a significant "reversibility cliff," where agents trained without external resets struggle and become trapped in irrecoverable states as environmental irreversibility increases, unlike episodic agents that maintain steady learning.
