Hexy (iPhone)

JensAlfke: Linked Vadim Anshelevich's name to the page for the Hexy that he wrote

Hexy for the iPhone (apparently no relation to the [[Hexy|Windows app]] of the same name) is a Hex game implementation by Sean Heber and Greg Nichols. It was released in November 2008, for purchase via the iPhone App Store.

Hexy supports board sizes of 11x11, 15x15 and 19x19. It allows a single player to compete against an AI (named "Buzzy"); or two humans can compete either on the same iPhone, or on two iPhones on the same local network.

There is no description of the strength of, or algorithms used by, the AI, although the game's credits screen thanks Jack van Rijswijck, Arthur Vause, [[Hexy|Vadim Anshelevich]] and Cameron Browne for "inspiration".

JensAlfke: Added disambiguation link to the iPhone app Hexy. Minor grammar fixes.

''(For the iPhone app also named Hexy, see "[[Hexy (iPhone)]]".)''

Hexy is a [[Hex]] playing program written by [[Vadim Anshelevich]]. It was gold medallist of the Computer Olympiads in 2000.

Its approach is based on [[virtual connection]]s.

JensAlfke: Added new Hexy iPhone app (which I'm not affiliated with). Restructured into a list.

This article enumerates diverse ways to exploit [[Hex]] with a computer.

== AI techniques used in Hex ==

*[[Minimax (computer)|Minimax]] and alpha-beta search were used by [[Queenbee]].
*[[UCT]] is used in MoHex.

== Programs with AI ==

There are several computer programs which play Hex.

=== Available programs ===

* The currently strongest available Hex program is [[Six]] by [[Gábor Melis]], running on Linux or Unix or Windows.
* The second strongest program available is [[Hexy]], running on Microsoft Windows. Hexy was the first program to use [[virtual connection]]s and was champion of the 5th Computer Olympiad in 2000.
* [http://www.cs.ualberta.ca/~queenbee/ Queenbee] by [[Jack van Rijswijck]] finished second that year.
* An iPhone app also named [[Hexy (iPhone)|Hexy]] (no relation), released in November 2008, offers an AI opponent; the AI appears to be a custom design and hasn't been rated.

=== Unavailable programs ===

* [[Wolve]] is currently the best Hex program. It is the gold medallist of 2008 Computer Olympiads.
* [[MoHex]] is a [[UCT|UCT-Monte Carlo]] Hex program developed at the [[University of Alberta]] by Philip Henderson, assisted by Broderick Arneson and Ryan Hayward
* [[Mongoose]] by [[Yngvi Björnsson]], [[Ryan Hayward]], Mike Johanson, Morgan Kan, and Nathan Po.

== Non playing programs ==

=== Front End ===
* [[HexGui]] is a graphical user interface designed by "ab", mostly used as a front end to play against Six. It is possible however to play against other programs that can communicate via [[GTP]]. It can be downloaded on "ab"'s web [http://mgame99.mg.funpic.de/havannah.php page].

=== Reviewing and Editing Programs ===

* [http://canyon23.net/jgame/README_hex.html JHex] by Kevin lets you analyse a game, and databases of games.
* [http://www.drking.plus.com/hexagons/hex/khex.html KHex] by David King is a tool for reviewing games. Very well suited for sharing commented games (it exports games in [[Smart Game Format]]!)
