(This # will not add to the time taken to check the pattern.) # ################# # # After the pattern, some supplementary information in the format: # # :trfno, classification, [values], helper_function # # These and other aspects of the pattern database are documented # in the Texinfo documentation. # ################# # # Any line beginning with #, or any part of a line following # whitespace is a comment. # # This database has the special property that there are stones # temporarily added at the very corners of the board when # called. This allows us to use pattern matching for the first real # stones in an empty corner but also means that the extreme corner # stones must be included in all corner patterns. # # There are no meaningful classifications that can be used in this # database. All patterns need to have a specified value, which is # related to the probability that the pattern will be used. Basically # a pattern which has a value being N higher than another pattern is # 2^N times more probable to be chosen. Additionally there are some # cutoffs involved, see engine/handicap.c for details. attribute_map value_only goal_elements none callback_data !
