★ /prog/ challenge No. 666 ★ (Easy)

Name: Anonymous 2013-01-07 12:41

THE CHALLENGE:
Implement ``Tohosort'' (http://www.freewebs.com/tohosort/) 66in Lisp99 in your programming language of choice.

Post the source code of your implementation. It should at least read the input from stdin and print a sorted list after making the comparisons.

Deadline: 2013-01-21 00:00.

The programs will be judged by elegance, speed and number of comparisons made using a random list that will be published the day of the deadline. The winner will be awarded with Ten (10) שקליםSuss (that's Suss-shekels for you goyim), which is enough to pay the fee needed to cross the Sanzu River by ferry.

Is this about the underlying algorithm? Then the number of comparisons should be invariant under various implementations.

sepples, PHP and Java(Shit) retards wouldn't get it right. But yes, I think it's just the algorithm.

Original code:


function fnc_Sort(int_SelectID) {
   // ステータスにより処理を分岐
   switch (int_Status) {
      case 0:
         // 初回クリック時、ソート情報を初期化する。
         init();
      case 2:
         // ソートが終了していた場合、ソート処理は行わない。
         return;
      default:
   }

   // ary_RecordDataに保存
   // 左側Count
   if (int_SelectID != 1) {
      fnc_CountUp(0);
      while (ary_EqualData[ary_RecordData[int_RecordID-1]] != -1) {
         fnc_CountUp(0);
      }
   }

   // 引き分けの場合のみ
   if (int_SelectID == 0) {
      ary_EqualData[ary_RecordData[int_RecordID-1]] = ary_SortData[int_RightList][int_RightID];
   }

   // 右側Count
   if (int_SelectID != -1) {
      fnc_CountUp(1);
      while (ary_EqualData[ary_RecordData[int_RecordID-1]] != -1) {
         fnc_CountUp(1);
      }
   }

   // 片方のリストを走査し終えた後の処理
   if (int_LeftID < ary_SortData[int_LeftList].length && int_RightID == ary_SortData[int_RightList].length) {
      // リストint_RightListが走査済 - リストint_LeftListの残りをコピー
      while (int_LeftID < ary_SortData[int_LeftList].length){
         fnc_CountUp(0);
      }
   } else if (int_LeftID == ary_SortData[int_LeftList].length && int_RightID < ary_SortData[int_RightList].length) {
      // リストint_LeftListが走査済 - リストint_RightListの残りをコピー
      while (int_RightID < ary_SortData[int_RightList].length){
         fnc_CountUp(1);
      }
   }

   //両方のリストの最後に到達した場合は
   //親リストを更新する
   if (int_LeftID == ary_SortData[int_LeftList].length && int_RightID == ary_SortData[int_RightList].length) {
      for (i=0; i<ary_SortData[int_LeftList].length + ary_SortData[int_RightList].length; i++) {
         ary_SortData[ary_ParentData[int_LeftList]][i] = ary_RecordData[i];
      }

      ary_SortData.pop();
      ary_SortData.pop();
      int_LeftList  = int_LeftList - 2;
      int_RightList = int_RightList - 2;
      int_LeftID    = 0;
      int_RightID   = 0;

      //新しい比較を行う前にary_RecordDataを初期化
      if (int_LeftID == 0 && int_RightID == 0) {
         for (i=0; i<ary_TempData.length; i++) {
            ary_RecordData[i] = 0;
         }
         int_RecordID = 0;
      }
   }

   // 終了チェック
   int_Status = (int_LeftList < 0) ? 2 : 1;

   fnc_ShowData();
}

Made in JavaShit without using trees. I'm sure I can make something better.

Let's see how finishes first.

Sadly. I know C but not Lisp. Well, Xarn would always win these challenges without using Lisp. only C and Allegro.

OP here. The program should receive the list of things you want to compare. That way, you can sort your preferences for fruits, movies or Jewish runes. The Touhou thing is just an example, this is the only ``comparator'' of this kind I know.

Also, no need to act like an imageboard frequenters ironically when you can participate and win the exclusive Suss-shekels.

Rare /jp/ visitor here.

Most of /jp/ are ``such a neet XD'' like you say. But a good bunch of /jp/ knows Japanese and would go to Japan only for touristic purposes. They hate the ``I CANT WAIT 2 MOVE 2 JAPNA!'' crowd, so I don't really understand why you're mocking them like that. They also hate that /b/-style posting you just used. If anything, /g/, /v/ or /a/ are the ones who love that posting style, not them.

It's funny because you said ``bear'' with us and there are hairy faggots who call themselves bears.

In any case, let's not shit up the thread, I haven't seen a /prog/ challenge in a good while. This may not be as interesting as other challenges but I'll probably give it a try. I really need to ``derust'' my Lisp skills.

Given an unordered set, optimally choose pairs a,b that when given some number of a>b / b>a or b=a equalities, returns an ordered set?

A rather interesting problem is minimizing the amount of comparisons you ask for using prediction. I thought up a few things but I'm too lazy to implement them.

>>25 (CC: >>24)
Yes, that's what Tohosort does, although I'm not 100% sure if that's the challenge. Well, it says Easy on the title, so it must be that. >>26's suggestion must be the somewhat interesting part.

Name: Anonymous 2013-01-09 10:32

I'm thinking of a non-deterministic way of doing it. Maybe randomizing the elements in the set would minimize the amount of comparisons made?

I should read my HtDP

Or you could just read anything about sorting algorithms. The problem is literally just sorting a list using pairwise comparisons; i.e. the way nearly every sorting does it.
You can store other people's results to create a partly sorted list (and choose a sorting algorithm that works better on partly sorted lists), but even that isn't very interesting.

Name: Anonymous 2013-01-09 11:05

But the user is the one who gives the result to compare(a, b), not the elements themselves. Every user will have a different way of sorting the set.

I don't know why you think that makes even the slightest difference. A comparison is a comparison, whether it's done by a mathematical function or an idiot clicking Chinese cartoon stills.

An idiot clicking Chinese cartoon stills is not a deterministic Turing machine.
