What is the definition of 'colouring' as applied to Sudoku?

Post by lac »

Whatever it is, I don't think I know how to do it. I am looking at
The Four Colour Theorem and Kempe chains ... am I reading about
the correct stuff?

Thanks,

Hi,

An explanation of colouring is not yet in my solving guide, but here is a link to a good explanation: http://www.simes.clara.co.uk/programs/s ... ique12.htm

There are more advanced colouring techniques, but they are not explained by Simes.
