knights-tour's Introduction

Knight's Tour

This program solves the Knight's Tour Problem, as stated by Euler. If you have a knight in a chess game, you can make it go through the whole chessboard without going twice on the same square, if the start square is well chosen.

This Prolog program (comments in french) solves this problem using the following heuristic : the knight should go to the square which has the littlest number of possible next moves. It can be used on chessboards of size 25x25 and it finds solutions in a sufficient response time.

Usage

swipl -s knights_tour.pl

Then answer the questions about the size of the chessboard, then type:

go.

knights-tour's Issues

Naive method not working

Hi,
When I commented the heuristic method and went on with the naive method, the code didn't work. After giving the command go., there was no output and the cursor kept blinking for a long time. For naive method also, we are supposed to compile code, answer the questions and then go, right? Is my way of execution correct? Correct me if I am wrong.

I have attached a screenshot of the output as a proof.
