Day 19

[reading: Orson Scott Card, "Shadow Puppets"]

This afternoon I got around to sitting down and writing my own sudoku solver. I had been toying with the idea of doing it as a Java applet, with animations and so forth, but in the end I went for a command line C++ version that only I will ever use (as there are already several web-based solvers out there, and my Java is pretty rusty). Angel's original page was a useful start, and I got as far as implementing the simple stuff (effectively techniques 1, 2 and a simple version of 5 from this page).
