Spotify Shuffle (music playlist shuffle algorithm) code-golf random Background Perfect shuffle algorithms like Fisher-Yates shuffle don't produce great results when it comes to music playlist shuffling, because it often produces clusters of songs from the same album. In an attempt to solve this...

@NewSandboxedPosts Random fact: I was once asked to implement this algorithm in an online job interview.

What happened with those downvotes in the sandbox?

I saw several consecutive proposals receiving downvotes w/o constructive comments

Howdy y'all. I'm thinking of posting this soon. Any ideas for improvement?

Bubbler

@Jono2906 How about the input AB(CD{EF]GH or AB(CD}EF]GH?

Jono 2906

@Bubbler I'll add those now

Bubbler

Oh, so we ignore ()s in terms of matching brackets.

Jono 2906

@Bubbler Yeah. I mention that this challenge is about grouping brackets []{}

Bubbler

@Jono2906 Then a follow-up question: how about AB[CD{EF]GH, AB[CD[EF}GH, and AB{CD]EF]GH?

Jono 2906

@Bubbler I'm going to have to think about that

Because the rules of the challenge and Keta's interpreter differ

Bubbler

I initially thought the algorithm to be: scan left to right, maintaining a stack of open brackets. If I meet a non-matching closing bracket, close the open one(s) until they match or stack is empty. If the stack is empty, put a matching open bracket at the beginning instead. If the stack is nonempty at the end of the string, close all of them.

@Jono2906 I believe ^ is more logical and actually interesting.

Also, for the tags, balanced-string would work.

@Bubbler that actually does sound like a better idea.

I'll have to look into that tomorrow (AEDT tomorrow)

Thanks for the feedback Bubbler! I appreciate it a lot!

@Bubbler turns out that's what the algorithm was anyway!

Sandbox bot is about to tell you guys about a thing in a few. Please take a look

Thought I should ask about this here before posting anything to the sandbox. I've just found this clever project which lets one control a flight in the game Kerbal Space Program using (theoretically) any language capable of sending TCP packets. There are libraries provided for C#, C++, Java, Lua and Python

Would a code golf challenge using this be acceptable here or would the necessity of setting up a modded installation of KSP be too far from standard code golf?

Veskah

21:02

I don't think so. There's been other TCP challenges

You might have to go the extra mile to validate answer though

The modded KSP requirement might garner you a few downvotes though. Will be tricky to write well

A: Sandbox for Proposed Challenges

He. Might. Go. All. The. Way. Touchdown! [in-progress] Premise: In American Football, a team has to drive up the field to their opponent's end-zone to score points. But here's the catch, they have 4 tries (called downs) to go at least 10 yards to gain a new set of downs. They repeat this unti...

senox13

@Veskah I don't know if you've played the game, but I was thinking of making the requirement be something like 'achieve a minimum 100 km orbit using a specific built-in ship', so that the challenge is writing the code, not designing a craft. I'll write up a rough draft and submit it to the sandbox. Just wanted to make sure this wouldn't be seen as a definite close by the community. Thanks for the input

Adám

@senox13 Another issue is that it requires a non-free product for participation.

senox13

21:25

@Adám Ah, hadn't even considered that aspect. Is that explicitly against the rules or more just looked down upon?

dzaima

21:59

@senox13 I don't think it's explicitly disallowed, but that's probably because noone has made a challenge that requires using non-free products yet

Hey, so what is the difference between 05AB1E legacy and new 05AB1E?

I mean, why need to completely branch into a new language?

Also, what was the main driving force behind the idea to make the split?

Bubbler

23:31

@Jono2906 I meant AB[CD{EF]GH --> AB[CD{EF}]GH because [] already match, not [AB[CD{EF}]]GH.

Jono 2906

@Bubbler ah. I thought that's what I'd done.

Ah.

That'll need fixing

Hmm
