EcoReason: A Graph-Guided Evolutionary and Negative-Aware Reinforcement Learning Framework for LLM Commonsense Reasoning

While large language models (LLMs) have achieved impressive gains in commonsense reasoning, they often fall into “associative shortcuts,” failing to distinguish correct answers from plausible but constraint-violating hard negatives. This reliance on semantic priors rather than specific situational constraints limits th...
