Yeh I have noticed that list already; my program counts 8153 puzzles. If they are all like the first two I will be off the street for a while.

it should count 8152
the first line is a magic identifier and record schema

Code: Select all

#!sudoku -c4,Q1,ER,XR,puzzle,label,Q1time,ERtime,Q1stats,stats

-c4, specifies one puzzle per line, puzzle in the 4th comma-separated field
Q1,ER,XR,puzzle,label,Q1time,ERtime,Q1stats,stats are the field names
in my solver the fields are accessed by %(name)f

True; I forgot to take into account that the last puzzle is duplicated in my system in order to prevent end of file reading problem.
