Running the experiment with a simple maze configuration

We start our experiments related to the creation of the successful maze navigation agent with a simple maze configuration. The simple maze configuration, while having the deceptive local optima cul-de-sacs discussed earlier, has a relatively straightforward path from the start point to the exit point.

The following diagram represents the maze configuration used for this experiment:

The simple maze configuration

The maze in the diagram has two specific positions marked with filled circles. The top-left circle denotes the starting position of the maze navigator agent. The bottom-right circle marks the exact location of the maze exit that needs to be found by the maze solver. The maze solver is required to reach the vicinity of the maze exit point denoted by the specific exit range area around it in order to complete the task...
