Stochastic dynamic programming is a way to solve problems that involves making decisions over a period of time. It uses math and computer models to figure out the best decisions to make in order to reach a goal. Think of it like a game where you have to decide what move to make in order to get to the end. Stochastic dynamic programming looks at all the possible choices and then figures out which one is the best. It helps us make better decisions, because we can see all the choices and pick the one that gives us the most success.
