Abstract
Proposes FlowReg, a neural ODE-based regularization method for reinforcement learning that aligns an agent's latent representation with the underlying environment dynamics by modeling MDP trajectories as ODE flows. Integrated into Actor-Critic algorithms, it improves performance across Atari environments.
Less Effort, Shorter Proofs: Reinforcement Learning for Security Protocol Analysis in Tamarin

Abstract
Presents a reinforcement learning framework for proof search in the Tamarin security protocol verifier, inspired by AlphaZero and AlphaProof. A stateless Tamarin API exposes proof search as a classical RL environment, in which Monte Carlo Tree Search is guided by a neural heuristic that learns from completed subproofs. Across 16 case studies, it finds more proofs automatically than Tamarin's standard search and produces shorter proofs than both the standard and human-engineered heuristics.
