OptiAgent: Multi-agent framework for end-to-end operations research optimization modeling
OptiAgent is a multi-agent LLM framework that converts natural language descriptions of Operations Research problems into solver-ready mathematical formulations and executable code. The architecture uses dedicated agents for extracting decision variables and constraints, with a multi-loop validation system featuring four specialized feedback mechanisms targeting distinct failure modes. The system claims state-of-the-art performance on 3 of 4 benchmarks spanning LP, MILP, and Nonlinear Programming tasks, while also improving transparency through auditable agent reasoning.

Democratizing Large-Scale Re-Optimization with LLM-Guided Model Patches
This paper introduces an agentic framework where an LLM acts as an operations research expert, translating natural-language user prompts into structured updates ('patches') to deployed optimization models and selecting appropriate re-optimization techniques from a toolbox. The toolbox leverages primal information—historical solutions, valid inequalities, solver configurations, and metaheuristics—to accelerate re-optimization while preserving solution quality. Experiments on supply chain re-optimization and university exam scheduling demonstrate computational efficiency gains and improved interpretability through patch-based model modifications. The framework aims to reduce dependence on OR experts for maintaining dynamic decision-support systems.
Agentopia: Long-term multi-agent life simulation framework for training LLMs on social behavior
Researchers introduce Agentopia, a framework for simulating 10 years of social life across 100 LLM-powered agents, enabling study of emergent social behaviors and long-term personal growth dynamics. The system defines a 'life reward' metric mirroring human well-being and uses it to train LLMs via rejection sampling. Training on simulated social experience yields a +15.6% improvement on downstream role-playing benchmarks, suggesting that synthetic social simulation can generalize to real capability gains.
agent-teams-ai: multi-agent orchestration framework with kanban-style oversight
A TypeScript open-source project on GitHub implements a multi-agent system where autonomous agents handle tasks, communicate with each other, and review each other's work, while the user supervises via a kanban board. The framework supports 200+ models across 75+ LLM providers including Codex, Claude, and OpenCode. It has accumulated 1,189 stars with 56 added today, suggesting growing community interest.
EvoSOP: LLM agents self-evolve by synthesizing atomic actions into reusable Standard Operating Procedures
Researchers propose EvoSOP, a framework enabling LLM agents to extract reusable Standard Operating Procedures (SOPs) from execution trajectories, effectively converting sequences of atomic tool calls into higher-order callable tools. The framework iteratively optimizes the agent's toolset through a lifecycle of construction, merging, evaluation, and pruning. Experiments show EvoSOP improves task success rates and reduces interaction rounds compared to static-toolset baselines, offering a scalable path toward self-evolving agents.
Benchmark and study of LLM agents in deliberative multi-agent collaboration under partial observability
Researchers introduce a scalable benchmark for evaluating LLM agents on cooperative joint decision-making tasks where agents must exchange information under partial and asymmetric observations to reach a shared decision. A systematic evaluation of representative LLMs finds that state-of-the-art models still struggle with complex deliberative collaboration, failing in either information alignment or downstream reasoning even with external mathematical tools. Diagnostic analysis also reveals that deliberation can enable reflection and error correction, sometimes outperforming centralized baselines, offering a nuanced picture of multi-agent LLM capabilities.
Multi-Agent Fictitious Play (MAFP) applies game-theoretic equilibrium-seeking to LLM decision-making
Researchers propose Multi-Agent Fictitious Play (MAFP), a multi-agent system paradigm that frames LLM-based decision-making as an equilibrium-seeking process borrowed from game theory. Each agent represents a stakeholder stance and iteratively best-responds to the empirical mixture of other agents' past decisions, addressing what the authors call 'stance entanglement' — mutual interdependence among stakeholder decisions that cannot be decomposed into independent subtasks. MAFP is evaluated on competitive strategy tasks and outperforms single-round and multi-round baselines on tournament strength and robustness metrics. The work extends the MAS literature beyond divide-and-conquer execution patterns into interdependent decision scenarios.
PCMA: Learning coordinated agent-specific preferences for multi-objective multi-agent RL
A new arXiv preprint introduces Preference Coordinated Multi-agent Policy Optimization (PCMA), a method for cooperative multi-objective multi-agent reinforcement learning (MOMARL) that learns agent-specific preferences to enable complementary trade-offs across agents. The authors formulate cooperative MOMARL as a team-optimal game and provide a first-order improvement decomposition showing that preference diversity can induce team improvement. Experiments on cooperative MOMA environments and a traffic-control scenario demonstrate improvements in both performance and trade-off coordination.
