# Choose one of algorithms:
# aswa - uses s_len=1 scan (SAS) inside sliding windows (SWA)
# rswa - Random Sliding Windows Approximation (random_seed and random_range are activated automatically). Shuffle not needed
# scan - full (or window) scan all possible combinations (can randomize starting vector with random_seed and random_range)
# SAS - Step-Appending Scan is subclass of window scan, where s_len=1
