Characterizing nonconvex boundaries via scalarization
Jin Ma, Weixuan Xia, Jianfeng Zhang
We present a unified approach for characterizing the boundary of a possibly nonconvex domain. Motivated by the well-known Pascoletti--Serafini method of scalarization, we recast th…

Convergence Analysis for Entropy-Regularized Control Problems: A Probabilistic Approach
Jin Ma, Gaozhan Wang, Jianfeng Zhang
In this paper we investigate the convergence of the Policy Iteration Algorithm (PIA) for a class of general continuous-time entropy-regularized stochastic control problems. In part…
