Was surprised to see how many people are reading my daily entries here. OK, needed to tidy it up a bit, and translated the most recent posts in English. Blogging is a dangerous activity. Before you know it, everybody is looking over your shoulder.

Finished the Scanning article in www.Sudopedia.org. May need some revisions, but at least it is a consistent story now. Still no cowriters.

I have isolated the 400.000 Sudokus in my Access database that can be classified as ‘easy’. I will run a special program today, that performs a solving speed test on these sudokus. This is something I found out recently. It is not only the requirement of solving techniques, but also the solving speed that determines the difficulty of a sudoku. For the lower grades, this is the most important benchmark. A whole series of sub-grades can be worked out.

But not for me. I have to keep up my reputation, so I will always supply sudokus that are a tad more difficult than the rest of them. This solving speed test will help me pick out the nice ones.
