The dan-level Life & Death algorithm of GoTools (by Thomas Wolf) is integrated into SmartGo. It solves enclosed Life & Death problems as fast as many dan-level players can, and often faster.
White can make a ko (0.92 seconds).
Black lives using an under-the-stones tesuji (0.01 seconds).
Wieso spielt SmartGo manchmal den falschen Zug in Leben & Tod Stellungen?
Even with the integrated GoTools, a dan-level Life & Death problem solver, SmartGo sometimes makes silly mistakes in Life & Death situations. There are a number of reasons why this can happen, including:
- GoTools may not have been given enough time to solve the problem.
- SmartGo didn't enclose the group properly before passing it to GoTools.
- SmartGo's heuristic evaluation didn't recognize that the group was weak, and thus never passed the group to GoTools.
- GoTools figured out that the group is dead, but SmartGo is not certain the surrounding group is alive, and may think it's a race to capture.
- GoTools returned the correct move, but SmartGo decided something else was bigger.
