I found that the posts could only be shown partly in any RSS reader, if I wrote is in English.
About Sudoku, I think everybody can finish the game in a short time if a lot of information is given. I found an M-file on Matlab’s homepage, which utilized the image processing.
[Actually, Google Goggles had done that before, but this time with Matlab.]
First, use image processing to import the sudoku game into text format.
Second, use traditional method to calculate the solution.
The GUI is concise and nice, I think it is a wonderful piece of work.
Also this piece of work could be extended to jigsaw Sudoku. I suppose.

I am thinking to convert images of PDE into text format, then use FDE or FEM to calculate the solution.
