Pathfinder Neural Network

I designed and created a neural network I dubbed 'Pathfinder' using PHP and the FANN Library. Pathfinder is an example of a neural network that is capable of plotting an 8 direction step path (cardinal points + diagonals) from a starting position in a 5x5 grid to an ending position in that grid.

To keep the Pathfinder example simple it is not trained to deal with walls or non-traversable terrain however it would be very easy to add that by adding additional training.

Pathfinder was accepted as an example of how to use FANN on the Official PHP FANN Github.

Online / JS Version

This version of Pathfinder is implemented using FANN.js and a live version is available on GitHub Pages.

Basic / PHP Version

This is the simplest example of Pathfinder and is the version that is included with the Official PHP FANN repo.

• pathfinder_train.php

• pathfinder_test.php

• pathfinder.data

Note PHP FANN is required for the code contained in this repo to run.
