Systematic Sudoku Human engineered Sudoku solving

Reviewed by Abd (talk) 12:08, 25 July 2019 (UTC)

"Human engineered" could mean two things: it could mean "designed and built by a human," which the blog certainly is, or it could mean that it reflects and studies and explains sudoku solving from a Human factors and ergonomics point of view. I think he intends the latter, but the blog is not a decent example of human engineering. It is an extensive explanation of what he found worked for him (and for some others), but that is very difficult to approach, as presented. He uses sequential candidate notation, covered below, and has analytical methods that are forbidding in appearance, such as the lovely diagram on the right.

To be fair, that diagram is, if I am correct, simply a record of a complex series of actions. Each action may be simple. But what is the purpose of the diagram? For what is it useful? There is relatively standard notation for listing such actions, which one could follow step-by-step if desired. That also looks complicated, but one can easily see that each step is simple. As well, a series of images, with highlights showing each step and annotated, would be simple to produce -- and I expect to do that. This would be pedagogically far more "human-engineered." --Abd (talk) 13:49, 28 March 2020 (UTC)
