Pawgo, you know we have talked in the past and I have tested your programs and posted results; I honestly do not know how the kangaroo stride version could help speed up search time or how to really implement it to work better than original kangaroo, as far as time finding key.
Kangaroo with stride is not for puzzles or other search, but for solving WIFs with missing beginning, you tested that:
https://bitcointalk.org/index.php?topic=5315607.msg56300590#msg56300590This is the situation where you know that answer is in the range A - B, but you do not test each key - stride is equal 58^x, where x depends on position of missing character.
It works, it solves given problem - but noone (at least not me) stated that it is somehow
better or faster than original one. It is just an add-on.
