1) in intelligent mode is solution faster if used only small hash memory (in Popeye default 2MB)
2) in brute force mode is solution faster with more hash memory, in Popeye for example with option -MAXMEM 100M
Problem is with clearing of hash memory. In intelligent mode programs cleared memory with ALL matting positions. For short problems is this linear time relative very long (if big memory), but with small memory not.
Remark: this paradox is NOT in new version of Alybadix 2001 for seriehelpmates and seriestalemates.
