Code that rewrites code [Challenge]

Name: Anonymous 2013-02-10 22:29

Write a program that accepts the source code of a program, and rewrites it to perform better, or adds new features. The output source must be significantly altered. The program must also accept it's own source as input. Applied iteratively, the program must not exhibit behavior of local maxima that plagues genetic algorithms within the first 10 iterations.

Difficulty: Moderate

Language: Any language is acceptable

Deadline: 2013.28.02

Prize: The winner will receive 15 BTC upon verification and a gift certificate to Shapeways, so that you may print your own trophy, and a years supply of Tab soft drink. Second place will receive 10 BTC and a glow-in-the-dark meme t-shirt from Hot Topic. Third place will receive 5 BTC and a free electronic copy of SICP. Last place will receive a 4chan Pass, so that s\he may return to the imageboards.

Judging criteria: Submissions will be judged first on their completeness, then on the efficiency of the outputted code, and finally on the elegance of both the program itself and the code that it outputs. Should any major bugs be found after submission, the submitter must resubmit his\her code in its entirety.

Making it perform better is plausible, but trying to think of a way to have it add new features automatically (or by reading some sort of schema) is making me want to throw up.

Help.

Your managers often ask you to either solve the halting problem or create strong AI? You either work at a very bad place or a very, very good one.

#include <stdio.h>
#include <time.h>

int main() {
    sleep(100);
    puts("Your program is shit. Please rewrite it in Lisp.");
    return 1;
}

Compile with cc minddicks.c -o mentidicks.
Run it as ./mentidicks filename.java filename.py filename.rb filename.js
Only accepts non-Lisp programs. Feeding it a Lisp program will cause undefined behavior.

OP are you sure you actually understand what you're asking here? I mean, fuck, the best work I've seen in this couldn't do much more than warn me when a piece of code I wrote might write past the end of a buffer.

This is a pretty easy task for most here actually. If you were as good as you claim to be, you'd already have a few solutions in mind. I'm not going to submit mine because unless you all sign an NDA though, as it contains secrets vital to my career.

Try reading SICP HtDP again.

hmmmmm it's a good challenge, but i don't think anyone has really managed to do this yet.. even just getting a piece of code to understand varX + 1 seems like it would need quite a few tricks
Surely it's not impossible though =)

What about main, puts, and sleep (whatever that is)? They're functions.

does not check if the input is LISP.
Doesn't need to. Passing in a lisp program has UNDEFINED BEHAVIOUR! YAIN'T RED DA STANDARD.
