#Universal Machine implementation

This is my implementation of the 2006 ICFP Programming Contest.

The first part of the contest is to write a Universal Machine according to the specifications in um-spec.txt. You can use sandmark.umz to test your implementation. Finally you can load codex.umz and continue from there. For more information, have a look at the contest page.

##How to run the code

Here's how you can run my implementation.

###Python You can use the native Python interpreter, but it will take a long time. Running the sandmark takes about 2 hours and 42 minutes on my machine.

python machine.py sandmark.umz
python machine.py codex.umz

Using pypy will speed things up a lot. Running the sandmark takes about 5 minutes and 6 seconds on my machine.

pypy machine.py sandmark.umz
pypy machine.py codex.umz

You can use test_machine.py to run some unit tests.

py.test test_machine.py

###C# You can run this on OS X or Linux using mono. First you need to compile it to an exe-file.

mcs machine.cs

Then you can run the exe-file. Running the sandmark takes about 3 minutes and 15 seconds on my machine.

mono machine.exe sandmark.umz
mono machine.exe codex.umz
