Summary

Description
English: Gadgets for an NP-completeness proof of graph 3-coloring, by reduction from 3-Satisfiability. The variable and clause gadgets are shown on the upper and lower left, respectively, and the right side of the figure shows the complete reduction for the instance (xy ∨ ~z) ∧ (~x ∨ ~yz) with three variables and two clauses. This reduction is from Oded Goldreich, Computational Complexity: A Conceptual Perspective, Cambridge University Press, 2008, Proposition 2.27, p. 81.
