The Game of Hex
Abstract
Hex is a two person game played on an
n x
n
board in which the players take turns trying to construct paths
from one side of the board to the other. It is known that there exists a
winning strategy for the first player, but no one has yet been able to find such a strategy
for any board larger than
9 x
9.
Despite this, one can ask the following two questions: "what is
the shortest path with which player one can guarantee a win?" and "what is the minimal
number of moves play one must make to guarantee a win?" These are questions
of
optimal play in the game and the primary goal of these
pages is to give lower bounds on answers to these questions
and provide a number of conjectures and "challenges."
