WebReduction from 3-Coloring instance: adding an extra vertex to the graph of 3-Coloring problem, and making it adjacent to all the original vertices. Following the same reasoning, 5-Coloring, 6-Coloring, and even general k -Coloring problem can be proved NP-Complete … In computer science, graph reduction implements an efficient version of non-strict evaluation, an evaluation strategy where the arguments to a function are not immediately evaluated. This form of non-strict evaluation is also known as lazy evaluation and used in functional programming languages.

WebThe purpose of this section is to obtain a reduction of graphs with respect to a given complete family. Some of the properties of graphs, such as graphs with at least s edge-disjoint spanning trees in [3,17,19]can be extended to arbitrary complete families of graphs.
