I recently wrote a page replacement solver for a few page replacement algorithms we study in Operating Systems. The cool thing I liked about it is that it can also come up with diagrams of the thing happening, not to mention solve all problems in my textbook.
The solution uses Visual Studio 2008. It contains the code and header files too, if you want to use it in a different IDE.
Note : Uses 7-zip for compression. Get it at : 7-zip.org
