Hello Everyone,
The 2005 Christmas project is a genetic algorithm (GA) that solves for
Santa's optimal flight path. The program uses the cities.dat file in
the IDL distribution. Some unique features of this project is that the
actual great circle distance is used by the algorithm and multiple GA
parameters can be changed by the user through a simple GUI. The final
route is then displayed in an object graphics window with the sunlit
earth for December 24, 2005 shown. The sleigh is marked by a red
glowing ball (Rudolph's nose?) which follows the path chosen by the GA.
As time progress the sunlit part of the earth is updated with the three
different twilight zones (astronomical, nautical and civil) distinctly
displayed.
The code is quite complicated so you can download it from here (look at
the bottom of the page).

Just extract the files somewhere in the IDL path and type
santasroute at the IDL prompt. Feel free to pass it around for
others to enjoy.
Thanks Again and Merry Christmas!
