Hi,
One question regarding the performance of the algorithm.
It's stated that for puzzle #120, the :
Expected time: ~2 months on 256 Tesla V100.
This is really mind boggling

. But does someone know how long it took (or a time approximation) to solve puzzle #115 using 4 Tesla V100 ?
To me it took (60/2^5)*(256/4)= 4 months, which is surely not reasonnable.
