There was problem asking to write n programs a0, a1, a2, ..., an-1, so that running ak outputs a(k+1) mod n, and the score is sum(len(ai))/n2. Lower score the better.

Lots of answers just have a format and with the format score can go as near as you want zero. Do they have order in this case?

Some cases that probably worth discuss:

  1. 1/n 2/n
  2. 1/n 2-n
  3. 1/n 0

    \$\begingroup\$ @user202729 I understand the frustration, but please be nice. "you're really unable to write clear English" is downright rude and not constructive in any way. Not everyone was raised in an English-speaking environment, myself included. Instead of simply pointing out someone's poor English, you could ask clarifying questions. \$\endgroup\$ Apr 4, 2018 at 19:09
  • \$\begingroup\$ @JungHwanMin ... I don't think that this is rude, just "point out a fact". The OP themselves also say that occasionally. \$\endgroup\$

  • \$\begingroup\$ @user202729 Perhaps you didn't intend to make it sound like that, but at least to me, it does sound a bit rude. There are alternative ways to "point out a fact" than to state it directly (which is often rude). E.g. "Your English is broken" vs "I am having trouble understanding your English." The latter is more indirect and sincere. \$\endgroup\$ Apr 5, 2018 at 2:17
  • \$\begingroup\$ @JungHwanMin Ok thanks. \$\endgroup\$

1 Answer 1


If two or more answers have the same score, the default tiebreaker is time - the first answer to reach that score wins. Note that this includes edits - if answer A is edited before answer B is posted, and they have the same score after the edit, answer A wins.

    \$\begingroup\$ @l4m2 I don't understand your question. Answers have concrete-valued scores, not theoretical score functions. \$\endgroup\$

  • \$\begingroup\$ I think, I'm really not sure but I think, this question is about challenges where answerers have come up with methods for getting arbitrarily good scores. \$\endgroup\$

    \$\begingroup\$ It might be worth noting that challenge authors may come up with their own tiebreakers. \$\endgroup\$

  • \$\begingroup\$ @l4m2 In the challenge that you are asking about, the score appears to be lim [n -> inf] Σ|a_i|/n². If multiple solutions have the same value for that limit (0), then a tiebreaker is used (either one specified in the challenge, or the default tiebreaker of first-past-the-post). The scores are concrete values here, which is a necessity on this site - otherwise, answers wouldn't be comparable, and there wouldn't be an objective winning criterion. \$\endgroup\$

  • \$\begingroup\$ @l4m2 Limits and values are not comparable, so if there was a situation where one answer's score was a limit and another answer's score had a value, there would be no way to decide which is more optimal, so the challenge would lack an objective winning criterion and therefore be off-topic by our rules. \$\endgroup\$

  • \$\begingroup\$ @l4m2 You can have a scoring method that scores by the asymptotic score, but it needs to be challenge-specific. \$\endgroup\$

    \$\begingroup\$ Sometimes when making a question the author doesn't know asymptotic score will appear, so there should be a default \$\endgroup\$
