Talk:LlListSort

Bubble Sort?

This script: <lsl> default {

   state_entry()
   {
       llOwnerSay(llList2CSV(llListSort([3,2,3,5,3,1,1,4], 2, TRUE)));
   }

} </lsl>

outputs

1, 4, 3, 5, 3, 1, 3, 2

both in LSO and in Mono. This means that the sort is not stable. Since stability is a characteristic of Bubble Sort, it looks like the claim of using Bubble Sort is not correct. --Pedro Oval 20:01, 5 April 2014 (PDT)

Good point. -- Strife ^{(talk|contribs)} 21:26, 5 April 2014 (PDT)

maybe... needs an extended example to see if LSL backwards ordering isn't the culprit

If it's in reverse order, it's not stable either. The reverse would be 3,1,3,5,3,2 but the actual result is 3,5,3,1,3,2 --Pedro Oval 12:39, 6 April 2014 (PDT)

doh, you're right... comb sort perhaps? looking at the ordering exchange seems more likely than insertion

Best option could be to pose this question on the scripting mail list, Kelly appears to prefer that channel for tech information dumps. The bubble sort presumption probably came from a function included with the viewer part of the source, but its comments describe list syntax and functions that never made it to LSL2. --ObviousAltIsObvious Resident 17:30, 6 April 2014 (PDT)
