Efficient Global Planning in Large MDPs via Stochastic Primal-Dual Optimization

no code implementations21 Oct 2022 Gergely Neu, Nneka Okolo

We propose a new stochastic primal-dual optimization algorithm for planning in a large discounted Markov decision process with a generative model and linear function approximation.
