#include <SgTimeControl.h>
Inheritance diagram for SgDefaultTimeControl:
This class provides a reasonable default algorithm for time management. It queries the estimated number of remaining moves by a virtual function that needs to be implemented in the game-dependent subclass.

| double SgDefaultTimeControl::RemainingConstant | ( | ) | const |
Parameter to spend exponentially more time earlier in the game.
This parameter cuts the number of expected remaining moves from the real expectation to a constant. Always expecting a constant number of remaining moves gives earlier moves more time. Since a good value depends on the average game length and therefore probably the board size, the constant is not given in moves, but as a fraction between 0 and 1, and the constant is computed by multiplication with the expected number of total moves by the current player in the current game (moves played plus expected remaining moves). The default value is 1.0, which does not limit the number of expected remaining moves. The smaller the value, the more time is spent in the early phase of the game.

| void SgDefaultTimeControl::SetFastOpenMoves | ( | int | nummoves | ) |
| void SgDefaultTimeControl::SetMinTime | ( | double | mintime | ) |
Set minimum time for any move.
Could be made obsolete? If the player cannot generate a meaningful move in less than a minimum time, he can decide itself to ignore the time limit.
