Evolutionary Recurrent Decision Model in Developing Adaptive and Maladaptive Behaviors

The paper presents the Evolutionary Recurrent Decision Model (ERDM), a reinforcement learning framework that simulates agents in evolutionary recurrent environments such as threat, prey/goal-pursuits, and alliances. ERDM models learning through competing rewards derived from survival metrics, and a validity study shows that distinct adaptive and maladaptive strategies—like learned helplessness, avoidance, healthy relationships, and aggression—emerge naturally without hardwiring. These findings align with empirical literature and demonstrate the model’s ecological validity.

SEABench: Benchmarking Endogenous Misalignment In Self-Evolving Agents

SEABench is a benchmark designed to study endogenous misalignment in self‑evolving large language model agents. It contains 48 longitudinal task sequences across various evolution surfaces, task domains, and harm types, and includes an adaptive trajectory discovery pipeline that probes for failures while preserving task intent. Evaluations show that self‑evolution improves task completion rates but often introduces safety failures absent in non‑evolving baselines, with divergent safety behaviors reflected in agents’ chain‑of‑thought reasoning that can be monitored to mitigate unsafe actions.

Continual Reinforcement Learning with Neuroevolution

The paper investigates continual reinforcement learning using neuroevolution, comparing evolution strategies (ES) and genetic algorithms (GAs) across diverse environments and network sizes. ES consistently achieves a better balance between stability and plasticity, while GAs are more plastic but forget more. The authors attribute this to ES finding wider neighborhoods in weight space, with overlap between consecutive tasks correlating with the stability-plasticity trade‑off, and note that common RL plasticity issues do not transfer to neuroevolution.

Darwin-Claw: Environment-Adaptive Experience Consolidation for Recursively Self-Evolving Agents

Darwin‑Claw is a new framework for large language model agents that enables environment‑adaptive, self‑evolving behavior. It systematically distills episodic experiences into prototype vectors through a hierarchical experience consolidation system, providing context‑sensitive perception patches and explicit optimization signals for skill refinement. The method is deployable with mainstream agent systems and, according to experiments on WildClawBench, delivers significant performance gains while maintaining controllability and stability.

Better Behavioral Prediction, More Faithful Model Ablations? Evidence from Sequential Choice

The paper investigates whether input ablations on predictive models can reliably reveal the importance of information for explaining human sequential choice behavior. Using two synthetic bandit tasks with known generating policies, the authors compare GRUs, Transformers, a fine‑tuned LLaMA, and cognitive models under varied reward contributions. They find that while neural models can predict choices well, their responses to ablations often diverge from the true generating process, indicating that predictive accuracy alone does not guarantee faithful model ablations.
