Link to algorithms descriptions

[Zverik]

After experimenting with the site one would be interested in algorithm details (especially after Jump Point Search :) So it'd be nice to have descriptions a click away from the page. Wikipedia will do fine. Both algoritms and heuristics need links.

Thanks for your suggestion. I'll consider adding the links :)

Hi @Zverik there is PathFinding.js documentation in the works, though the sections on algorithms is yet to be written. You might want to keep an eye on this.
