Thanks, this looks interesting and I may investigate it further. Side question--are you aware of any notation methodologies for tracking "forbidden pairings" in multi-variable input situations? For instance, the project you linked lists an example test_set generation as: > test_set = all_pairs( > [1, 2, 3], ["low", "mid" ,"high"], [1.0, 3.7, 4.9], [:greedy, :relax, :optim] > ) How might I use mathematical or code notation to store the fact that "low" is an invalid pairing with "1.0" and ":greedy", which then invalidates all combinations including that pairing and reduces my total scope?
