Co-Evolving Acting and Forecasting for Language Agents

The paper introduces CoPE, a method that trains language agents by adding multi‑step action targets to the policy backbone. By supervising each action forecasted from preceding histories, CoPE enables acting and forecasting to co‑evolve without extra inference cost. Across five benchmarks, CoPE outperforms existing RL baselines, achieving up to twice the sample efficiency on ScienceWorld and improving overall performance on realistic applications.

HarnessMDP: Learning to Control LLM Agent Harnesses with Offline Reinforcement Learning

HarnessMDP is a learning-based framework that treats the execution harness of large language model agents as a learnable control layer. By formulating agent execution as a finite-horizon Markov decision process, the harness learns to select structural execution actions from the evolving agent state, using offline reinforcement learning from collected trajectories. Experiments on coding tasks, tau-bench, AgentBench, and other evaluation settings show that HarnessMDP consistently improves execution behavior and final task performance over baseline harnesses.

Falsification-proof non-market allocation mechanisms

The paper examines allocation mechanisms that rely on manipulable characteristics and shows that naive optimal rules lead to falsification and inefficiency. It characterizes optimal falsification‑proof rules across various falsification technologies and identifies an honesty condition under which these rules solve the planner’s unconstrained problem of maximizing a weighted sum of allocative surplus and agents’ welfare.
