Abstract

Recall the example on page 3, in which we transcribed in clauses the problem of checking whether a graph G with n vertices is k-colourable. We used n × k variables with the intention that each variable X ij abbreviates the phrase “vertex i has colour j”. Each variable X ij also represents the question “does vertex i have colour j?”, and intends to contain the yes-no answer to this question.
