Maze - simpler

The maze input and procedures are now simpler.

It is also easier to play without programming.

Give it a try.

Maze needs key

The robot now needs a key to escape from the labirinth:

The Pledge algorithm is no longer sufficient to ensure a successful exit.
How will you solve it? Here's one way.

Pledge algorithm

The Pledge algorithm can help you walk around obstacles and escape 2D mazes where the exit is located at the outer edges.

Escape using the Pledge algorithm

You can now find the Pledge algorithm implemented in Prequel and use it to help the robot escape the labirinth, once the key is found.

Without Ariadne

How about you? How would you escape from a labirinth?

Would you walk around randomly, risking to run out of energy before making your way out?
Or do you have a better strategy?

Unlike labirinths found in the puzzles section of newspapers and magazines, this robot does not have a map to provide him with a bird's-eye view of the problem.
This is the setting for my most recent challenge: the information required to find the exit is not immediately available...
Instead, it must be gathered as you move step by step through the maze, touching the walls to determine whether the path continues forward or to the left or to the right.

Once you play enough times, consider coding your way of solving it in Prequel, creating a Prequel bot.

The generated mazes cannot be solved by a simple wall follower strategy.
However, since the exit is always located at the outer edge of these 2D mazes, the Pledge Algorithm is suitable to solve them efficiently, once the key is found.

Currently, there are two Prequel bots on the GitHub repository, both are variants of a random walk.
Pull requests for Prequel bots with different strategies are welcome.
