Explicit Posterior-Sampling Planner NEW
Problem
Agents that rely on ad-hoc heuristics explore poorly, wasting tokens and API calls on dead ends.
Solution
Embed a fully specified RL algorithm—Posterior Sampling for Reinforcement Learning (PSRL)—inside the LLM's reasoning:
- Maintain a Bayesian posterior over task models.
- Sample a model, compute an optimal plan/policy, execute, observe reward, update posterior.
- Express each step in natural language so the core LLM can carry it out with tool calls.
How to use it
Wrap the algorithm in a reusable prompt template or code skeleton the LLM can fill.
