SimplEvo lets embodied agents retain task guidance and lessons from their attempts in two text memories, without changing model weights or delegating execution to a controller. Memories are learned during training and fixed at test time. In simulation, success rate reaches 81.7% on EBench, up from 46.7% under direct control; evidence is limited to two simulated benchmarks, not physical robots.
