How do I find Waldo with Mathematica?
This was bugging me over the weekend: What is a good way to solve those Where's Waldo? ['Wally' outside of North America] puzzles, using Mathematica (image-processing and other functionality)? Here is what I have so far, a function which reduces the visual complexity a little bit by dimming some of the non-red colors: whereIsWaldo[url_] := Module[{waldo, waldo2, waldoMask}, waldo = Import[url]; wa
Computer algebra system to simplify huge rational functions (of order 100 Mbytes)
I have a huge rational function of three variables (which is of order ~100Mbytes if dumped to a text file) which I believe to be identically zero. Unfortunately, neither Mathematica nor Maple succeeded in simplifying the expression to zero. I substituted a random set of three integers to the rational function and indeed it evaluated to zero; but just for curiosity, I would like to use a computer a
