SimSkill: A Self-Evolving LLM Agent for Skill and Knowledge Accumulation in Traffic Simulation

Read the original on arXiv AI →

SimSkill is a self‑evolving large‑language‑model agent designed for the SUMO traffic simulator. It continuously detects capability gaps, creates and solves environment‑grounded tasks, verifies solutions via an action–critic loop, and stores experiences in episodic, procedural, and semantic memory. Evaluations on two held‑out benchmarks across three LLM backbones show up to a 25‑percentage‑point improvement in verified success, with procedural and semantic memory contributing complementarily.

SimSkill: A Lifelong Learning AI Agent for Autonomous Mastery of Traffic Simulation

SimSkill is a lifelong learning AI agent that uses the SUMO traffic simulator to autonomously identify gaps in its capabilities, generate and solve tasks grounded in the environment, and verify solutions through an action‑critic loop. It consolidates experience into episodic, procedural, and semantic memory without updating its backbone language model, creating a reusable library for traffic‑simulation workflows. Evaluations on two benchmarks with three different LLM backbones show that SimSkill can improve verified completion rates by up to 25 percentage points, with procedural and semantic memory contributing complementarily to performance.

TerraZero: Procedural Driving Simulation for Zero-Demonstration Self-Play at Scale

arXiv:2607. 13028v1 Announce Type: cross Abstract: Training robust autonomous driving agents requires a simulator that is fast enough for reinforcement learning at scale, realistic enough to ground behavior in real-world map structure, and diverse enough to cover the safety-critical long tail that logged data rarely contains.
