The program guarantees 100% correctness of its solutions, and it can also analyze whole games, scanning them for tesuji.

MadLab comes with 997 capture problems extracted from real high-level games. The 997 capture problems can also be freely downloaded as SGF files here: [ext]

Example of an open-space capture problem (Lucky's Problem):

The problem is open-space since the marked stones are not surrounded by outer walls of stones like semeai or tsumego problems. MadLab is aimed at open-space capture problems, and the engine is based upon the so-called Lambda Search algorithm.
