This is a list of unofficial, deadline-less (hence not searchable) bounties offered by users on various challenges on the main site.

Disclaimer: There is no guarantee that the user will award the bounty for you in case you fulfill its requirement. Especially if the user isn't an active member anymore. The only guarantee is his/her written word.


Guidelines for updating

  • To add a bounty, create an answer.
    • Answers can be sorted to see which bounties are newest.
    • Answers can be commented on, allowing someone to notify the bounty's creator that the bounty may have been earned.
  • If a bounty is awarded, delete the answer.

    \$\begingroup\$ This would be much more useful if people posted answers as answers rather than editing them into the question. That way when I see that it's changed I could just look at the answers sorted by activity (which is my default sort order on PPCG) rather than having to view the edit history of the question. \$\endgroup\$ – Peter Taylor Jun 30 '16 at 7:34

    \$\begingroup\$ There's a TNB feed for these bounties now. In order to pick your bounty up, you have to add an answer to this question. Question edits and answer edits won't be picked up by the feed. \$\endgroup\$ – Dennis Oct 22 '16 at 17:36

    \$\begingroup\$ Bounties that are only present in the meta question, and not posted as separate meta answers, leave no way to contact the bounty poster when time comes to claim the bounty. Please consider posting an answer if you have a bounty offered that doesn't yet have a meta answer. \$\endgroup\$ – trichoplax Oct 24 '16 at 0:49

    \$\begingroup\$ Since the problem of stuff being posted in the question wasn't fixing itself, I've taken extreme action. If people want to sort bounties by amount offered, there are plenty of stack snippets which produce a table based on the answers: one of those can be adapted. Similarly, checking whether users are "active" or "passive" can be done with the SE API. \$\endgroup\$ – Peter Taylor May 7 '18 at 10:34

    \$\begingroup\$ @PeterTaylor It should be noted that not all the bounties in the question had corresponding answers, so you may have removed some completely. \$\endgroup\$ – mbomb007 May 10 '18 at 20:34
  • \$\begingroup\$ @mbomb007, I checked the first dozen manually and then I counted and reasoned that since there were considerably more answers than lines in the question I was wasting my time. \$\endgroup\$ – Peter Taylor May 10 '18 at 22:40
  • \$\begingroup\$ @PeterTaylor As an example, randomra had some bounties, but this search shows he has no current answers. Maybe you could write a script? Or ping everyone who had a bounty in the question, and they can deal with their own bounties. \$\endgroup\$ – mbomb007 May 11 '18 at 3:25

200 rep for a low-entropy maximal discrepancy-2 sequence

Compress a maximal discrepancy-2 sequence is about compressing a particular discrepancy-2 sequence.

Maximal discrepancy-2 sequence with minimal entropy is about finding a maximal discrepancy-2 sequence that's easier to compress.

This bounty will be awarded to an answer meeting all the following conditions:

  • It is the shortest answer to question 2
  • It is at least 3 bytes shorter than the shortest answer to question 1
  • Both of the above remain true for 1 week.
\$\endgroup\$
  • \$\begingroup\$ Does it have to be three bytes shorter than the shortest answer overall, or just 3 bytes shorter than the shortest corresponding answer in the same language? \$\endgroup\$ – Dennis Nov 29 '18 at 1:01

200-400 rep for discompassionate geometry

Construct a pentagon avoiding compass use is about finding a compass-and-straightedge construction of a regular pentagon while minimizing the number of circles drawn.

The Poncelet-Steiner theorem says that any construction possible with a compass and straightedge is possible with one circle, its center, and a straightedge. Finding such a construction is another matter.

Because the construction rules in this challenge are slightly different from the premises of the theorem (arbitrary points cannot be drawn in this challenge, which necessitates a second circle to construct anything nontrivial), it will not be valid for that challenge. Nevertheless, 200 rep goes to the first answer to that challenge that both:

  • Contains a construction in 1 circle (which necessarily includes adding arbitrary points) and makes a reasonable effort to golf the number of points and lines drawn
  • Also contains a valid solution or a proof of optimality of the current best solution.

If the answer is an improvement on the current best or a proof of optimality, I will award an additional 200 rep.

500 reputation

500 reputation by Mego in Seriously, GolfScript, CJam, or Pyth? for finding a solution using pattern matching or something similar (no running the input through the interpreters and checking the result) that correctly identifies all of the test cases in the question.

I already did the trivial solution of running the interpreters. I'd like to see a smarter solution - one that actually decides which language(s) the program runs in without running the interpreters. All test cases must pass correctly - that includes the Silver and Gold tiers.

150*3 rep for answers in Factorio (a non-free game)

I'll award at least 150 rep to the first 3 answers in the latest version of vanilla Factorio without using commands, custom scenarios, etc, that:

  • It is nontrival: either the shortest answer of all languages has at least 3 bytes, or you have used more combinators (or other structures that compute or generate things; poles and input don't count) than the number of input.
  • I can't come up with a better answer in the same version. For code-golf questions, being better means both the grid size and the blueprint string length are smaller. I may not have enough time to play it, so this may take a while.
  • Nobody else come up with a better answer while I'm looking at it. And no such bounties were awarded to the same question.

200 rep if it used at least 8 combinators, or 250 rep if it used at least 15.

I'm not sure there is a consensus about the I/O, but I'll try to use a format as close to the original answer as possible.

If there are less than 3 answers satisfying the criteria before Mar 31, 2019, I may (or may not) choose to award to any (previous or later) valid Factorio answers, even without satisfying the criteria. The bounty will be still open if less than 3 bounties are awarded.

  • \$\begingroup\$ Man, I've never tried to use the electronics in Factorio. I will give this a try though \$\endgroup\$ – Jo King Nov 13 '18 at 7:21
  • \$\begingroup\$ Note: I'm quite inactive in both PPCG and Factorio recently. It's not that I was away from PPCG to play Factorio... But that I'm afraid of forgetting how to golf in Factorio if I don't play it for too long. And it's not easy to find a good question for Factorio. \$\endgroup\$ – jimmy23013 Dec 10 '18 at 10:56

100 or 200 rep for significantly outgolfing me in BitCycle

I am offering the following bounties for outgolfing any of my answers in BitCycle:

  • Outgolfed by 25% or more: 100 rep
  • Outgolfed by 50% or more: 200 rep

Only one person can win the bounty for a given challenge. I may give more than the listed amount if the golf is especially clever or invents a new approach for golfing in BitCycle.

Edit: I have adjusted the percentages a bit. I also removed the 50-point bounty, since I found out you can't give 50 points on a question that you've already answered.


Previously awarded:

  • \$\begingroup\$ The listing is old, but do trivial golfs (e.g. "unnecessary ...") count? Also, is this dead by now? \$\endgroup\$ – Erik the Outgolfer Mar 23 at 15:14
  • \$\begingroup\$ Still active, and yes, trivial golfs count. That's why I did the increasing bounty amounts for different percentages. If you're just able to squeeze a few spaces and go from 50 bytes to 45, that's worthy of a small bounty, but going from 50 to 30 by changing the approach is more impressive. \$\endgroup\$ – DLosc Mar 26 at 1:13

  • \$\begingroup\$ @JoKing Yes, I'm planning to. I just don't want to be too hasty about it, or I'll end up in the poorhouse! ;) \$\endgroup\$ – DLosc Mar 28 at 2:14
  • \$\begingroup\$ @JoKing Feel free to post some yourself, too. ;D \$\endgroup\$ – DLosc Mar 28 at 2:26
  • \$\begingroup\$ Perhaps add some sort of delay, like "The solution has to be posted at least one week after the last edit to my answer"? As for posting them myself, I quite enjoy the language (2D languages are my jam!), but is there any way to do ASCII output? I feel like this language needs a quine. \$\endgroup\$ – Jo King Mar 28 at 3:39
  • \$\begingroup\$ @JoKing Hm, the one-week wait is an idea. Let's take the language-features discussion to the Esoteric Programming Languages chat room--I've asked for it to be unfrozen. :) \$\endgroup\$ – DLosc Mar 28 at 6:37

500 rep for a SILOS submission of a 2048 clone.

I'll even throw in a bonus 250 rep bounty (and of course give a week of bonus visibility). for one that has gui output (this is harder than it sounds). Feel free to use the developer tools, which integrate into this language nicely.

50 rep for outgolfing me in the language (ping me in the nineteenth byte, and give me one week to attempt the challenge.)

So that you can police me, we both submit our submission concurrently.

50 rep for the shortest "Hello, World!" in Pepe

If you can beat this, I will pass a 50 bounty for you.

I don't really believe a shorter solution exists - prove me wrong and you'll get it. My solution uses character constants which are probably the shortest way to push a number in Pepe. However, they are binary, so they span a lot of bytes - outgolfing it might be possible. Another problem is that most function pop the stack by default...

  • If it will be really hard (it will), I'm might even pass a 100 rep bounty.

250 and 500 rep for the next two decent TIO Hello, World! golfs

"Decent" here meaning in beating any solution on this page by at least 25%. Bounty may be awarded if under 25% if solution is especially impressive (subjective) - for example, if golfing in a language is particularly difficult.

Note: jimmy23013 appears to be on track to claim both bounties right now - they will probably be awarded after the current one ends unless a more impressive solution appears.

50 - 100 rep for Flattening the Cube

I posted this challenge in May 2017, and so far my answer is the only one. I'm offering a 50 rep bounty for the first answer that outgolfs mine.

In addition, I'll raise the amount to 100 rep if your submission is written in either Jelly or Add++, as I've already tried with both of these and haven't been able to finish.

To claim the bounty, just post an answer on the challenge, and optionally ping me in The Nineteenth Byte, or comment on this answer.

2000 rep for a Pain-Flak quine that uses the forward backward nature of the language.

100 rep for an answer to Shortest code to produce non-deterministic output in Tamsin

The Tamsin specification describes no mechanism for non-determinism. However, there is a compiler from Tamsin to C; it might be possible to use a bug in this compiler to generate C code that invokes undefined behavior (this behavior wouldn't manifest on TIO because it uses the interpreter rather than the compiler). I'm not sure whether this is possible, but if somebody demonstrates a solution, I'll award an 100-point bounty.
