To import learn file you do this: (snip from readme.txt) ------------------- Learning -------- Yace can profit from positional learning. When you have an entry pos_learn 1 in yace.ini this feature is enabled. From version 0.99 this is enabled by default. To disable, use "pos_learn 0". When Yace is still close to the opening book (currently whithin 15 moves after the last move from the book), and the score drops significantly, Yace will save some information to the files learnpos.bin and learnpos.yac. When in a later game a similar situations arises, Yace should be able to avoid the bad position in advance. The file learnpos.yac is an ASCII text file. If you should receive such a file, you can import the information by typing import_pos learnpos.yac Any other filename works as well, as long as the information in the file is in the correct format. Yace will not write to its learn files, when in Analyze mode, or when the game did not start from the initial start position. ------------------ Also if you have more than 10000 position in learned file you might wanna do this: ------------------------------------------ (snip from NEWS.txt) Added a command, to change the maximum size of the file poslearn.bin. By default, this has space for 10000 positions. To resize this, start Yace in text mode and type posentries 20000 to change the size to 20000 positions. Only making the size bigger is supported. Note, that Yace will need 16 bytes of memory for each position. Note, that this command must only be used once, don't put such a line into yace.ini. --------------- Mine is set to 50000 position. I have a question about this command, when I tell Yace to set the posentries to 50000 where does it save the info, so that it knows what to do next time? Cheers, pavs
