GTP

Hex GTP (or simply GTP) is a text-based interface for interacting with Hex software. A typical use is to separate front-end software, which provides graphical display of game boards, from back-end software, which implements a Hex strategy engine. The use of a standardized protocol in principle permits any strategy engine, such as Six, MoHex, or Wolve, to be plugged into any graphical front-end, such as HexGui.

Moreover, GTP can also be used by humans to interact with a strategy engine directly, i.e., without the use of a graphical front-end.

History

Hex GTP is based on the Go Text Protocol (GTP), which was originally developed for Go as part of the GNU Go software.
