INTRODUCTION Establishing global properties of a dynamical system is generally nontrivial problem. The most successful approach to the problem is the direct Lyapunov method [l]. However, the method Weband propose a novel Lyapunov approach to solve it. While the main challenge of other Lyapunov-based methods is to design a Lyapunov function candidate, we propose an LP-based algorithm to construct Lyapunov functions w.r.t. generic CMDP constraints. We also show that our method is guaranteed to always return a feasible policy, and under …
