POMDP Agent Simulator

Agentic reasoning is formalized as a POMDP with explicit reasoning traces:

π(z, a | h) = π_reason(z | h) · π_act(a | h, z)

Partial Observability: Agent cannot see full environment state, only observations
Belief State: Probability distribution over possible true states
Reasoning (Z): Internal thinking before committing to action
Action (A): External action taken based on reasoning

"This decomposition highlights the core shift: performing computation in Z (thinking) before committing to A (acting)."
