Constructor & Destructor Documentation

GoUctState::GoUctState ( unsigned int  threadId,
const GoBoard &  bd 
)

Constructor.

Parameters:
threadId The number of the thread. Needed for passing to constructor of SgUctThreadState.
bd The board with the current position. The state has is own board that will be synchronized with the currently searched position in StartSearch()
