Detailed Description

A GoRegion contained in a.

See also:

GoRegionBoard.

A GoRegion is a maximal connected set of points surrounded by stones of the same color.

Regions compute properties such as 1-vitality, 2-vitality [Mueller 95, p. 62-63],[Mueller 97b]. They are used for static and search-based safety solvers. They are also used for better move generation, e.g. in semeai.
