::: It sounds like you've got a decent idea of what you're going for here, though maybe you should split this into two tasks - overhand and riffle shuffles are different algorithms? --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 16:43, 28 April 2015 (UTC)
::::I find myself saying "yep" a lot reading this. I guess I was thinking it'd be more fun if some of those things were left open but I can see how a little bit more specification might make it better.
::::For the question on if a language has one built in I guess once we hammer out the details we want for whatever shuffle method is in this task(s) it will be easier to decide if the built-in satisfies it. I'm all for leaving it unadorned if it does what we ask.
::::For the riffle-specific questions I think I spelled out the "perfect" version of it in my response to Paddy. That can be reworked to add whatever details we decide we would need. I thought the "perfect" version of whatever sort we have would be pretty deterministic or have clear places where random numbers are needed. In the case of the riffle shuffle I described, the "perfect" version is 100% deterministic while the bonus "human imperfections" allow for randomness.
::::For the overhand-specific questions it isn't really described anywhere how many times you need to cut so I picked 5 (20% each time). I think that's a reasonable choice for a deck of cards so that would be my choice for the "perfect" version of that. That also makes it deterministic. Once again the randomness comes in with the imperfect cuts humans make. So that's where the random numbers come in.
::::A split isn't out of the question either. I guess we could start with both of the shuffles I described and see if anyone makes any others. I think we should make them subpages of [[Card shuffles]] if we do that though (e.g. [[Card shuffles/Overhand]] and [[Card shuffles/Riffle]]). Since these are based on shuffles used for playing cards I think it would be good to group them separately from more CS-oriented shuffles like [[Knuth shuffle]]. --[[User:Mwn3d|Mwn3d]] ([[User talk:Mwn3d|talk]]) 17:28, 28 April 2015 (UTC)
