An implementation of Tak and a computer opponent in C https://git.l-3.space/cgit/ctak/atom?h=main 2026-08-28T18:37:41Z 2026-08-28T18:37:41Z tslil clingman tslil@posteo.de 2023-01-15T15:03:37Z urn:sha1:ee216c008a188a9436fedb85c70ee5d1719733b1 Gone is the convolutional neural network, for it turns out not only is it more difficult to train, but all of the extra information about board layers didn't make much of a difference at this size. So cnn1986 has been replaced by nn1986, a standard, two-layer, dense nn configured as a binary classifier and (mis)used in that capacity. Note: total number of parameters is unchanged. HARK: this new nn exposes a bug somewhere in ctak. Run ctlm with self-play to see the completely borked board state at the end.
