Closed-loop solvability of infinite-horizon stochastic linear-quadratic problem for Markov regime-switching jump-diffusion system

This paper investigates a class of stochastic linear-quadratic (SLQ) control problems over an infinite horizon for Markov regime-switching jump-diffusion systems. Unlike classical diffusion models modulated by a Markov chain, we assume that the state process undergoes abrupt jumps that are synchronous with the regime s...

Model-Free Q-Learning for Infinite-Horizon Stochastic Linear Quadratic Problems with Regime Switching

On-policy and off-policy Q-learning algorithms that learn the optimal controller solely from online state trajectory data are developed, specifically developing on-policy and off-policy Q-learning algorithms that learn the optimal controller solely from online state trajectory data.
