Web9 jul. 2024 · The Markov decision process, better known as MDP, is an approach in reinforcement learning to take decisions in a gridworld environment. A gridworld environment consists of states in the form of grids. The MDP tries to capture a world in the form of a grid by dividing it into states, actions, models/transition models, and rewards.

WebA Markov decision problem (MDP) is the problem of calculating an optimal policy in an accessible (observable), stochastic environment with a transition model that satisfies Markov property (i.e., the transitions depend only only the current state, and not the states that the agent visited on its way to this state).
