int HexUctUtil::ComputeMaxNumMoves

(

)

RAVE is more efficient if we know the max number of moves we can have.

Simply returns FIRST_INVALID.

void HexUctUtil::GoGuiGfx	(	const SgUctSearch &	search,
		SgBlackWhite	toPlay,
		std::ostream &	out
	)

Print information about search as Gfx commands for GoGui.

Can be used for GoGui live graphics during the search or GoGui analyze command type "gfx" after the search (see http://gogui.sf.net). The following information is output:

• Move values as influence
• Move counts as labels
• Move with best value marked with circle
• Best response marked with triangle
• Move with highest count marked with square (if different from move with best value)
• Status line text:
  • N = Number games
  • V = Value of root node
  • Len = Average simulation sequence length
  • Tree = Average/maximum moves of simulation sequence in tree
  • Abrt = Percentage of games aborted (due to maximum game length)
  • Gm/s = Simulations per second

    Parameters:

    	search	The search containing the tree and statistics
    	toPlay	The color toPlay at the root node of the tree
    	out	The stream to write the gfx commands to
