I want to generate n sets of 6 random integers from 1->70 where each set of 6 integers sums to 172
Here's my first try: ts =: 3 : 0 b=: 2 6$0 for. i.y do. a=:1+6?70 b=:b,a end. b#~172=+/"1 b ) Test it: ts 1000 27 60 5 24 53 3 38 35 3 15 57 24 16 29 19 50 4 54 This generates some 6-element vectors that sum to 172 by elimination, but I don't have control of how many vectors it produces. I want to change the logic in the loop so that it keeps generating sets of 6 random integers, testing whether they sum to 172, saving just the sets that sum to 172, until I have saved y random sets that sum to 172, and then exits. Any help would be appreciated.
