What is SSDFs opinion on so called “killer libraries”, opening libraries that are specifically tuned to give good results when playing against certain other computers?
We don’t like them, but there is not much we can do. If we disqualified results from games played with such a library, then surely someone would protest against that. The best method is likely to be the one we described above: make sure each program under test gets to play against as many different opponents as possible, including older programs.
