## Ghosts

This is a JavaScript implementation of the board game "Phantoms vs Phantoms",

also known as "Geister".

https://boardgamegeek.com/boardgame/2290/phantoms-vs-phantoms

Notice that the "Geister" and "Phantoms vs Phantoms" rulesets differ in

one major way: In "Geister" the board is 6x6 and you're trying to exit

the board by moving _off_ of one of the corners.

In "PvP" the board is effectively "6x6 with the corners cut off,"

and you're trying to exit that truncated board by moving _into_

one of the corners (which are never inhabited during the game proper).

I find the "PvP" rules easier to teach, slightly quicker to play,

and certainly easier to make the UI for, so that's what I've

implemented here.

The AI player is currently based on the paper "Developing geister algorithms without machine learning"

("機械学習を用いないガイスターの行動アルゴリズム開発") by Koki Suetsugu and Yusuke Orita.

It is not very strong compared to a human player.
