Problem 44353. Group-wise Euclidean distance

Banned cheater solution.

if you are feeling overwhelmed by a particularly persistent cheater just know that you can ban a player from your own problems by adding to your testsuite something like: lines=textread('groupDist.m','%s'); id=str2num(regexp(lines{end},'\d+','match','once')); assert(~ismember(id,[123456789 234567890]),'banned player id'); (where the array in the ismember line contains the list of player ids that you want to ban from your problem -e.g. my player id is 1379371; please do not ban me :)

Many thanks Alfonso for your suggestion. I was just thinking if I can ban a persistent cheater based on the player id. What you suggested is exactly what I need. If this guy cheats one more time (which is getting harder now with my added pcode in the test suite), I will definitely ban the guy using your suggested code.
