Ever wondered how a robot decides its next move in a maze?
Imagine a robot navigating a maze to find an exit. It can't see the whole maze at once and must make decisions based on limited information.
The robot uses a rule to choose its next step, considering the immediate outcomes of its actions. This rule helps it make the best choice at each point to reach the exit.
Example
If the robot is at a junction with one path leading to a dead end and another to a room with two more exits, it chooses the path with two exits, hoping it leads closer to the exit.
Remember this
The robot's decision-making process is guided by the Bellman equation, which helps it evaluate the best action to take at any given moment.
