3-coloring - Wikipedia
3-coloring may refer to: Fox n-coloring, in knot theory, a method of colouring knots or links. Tricolorability, in knot theory, the property of being represented by three colours. Graph …
Max-3Cut: Color with 3 colors, make the coloring as legal as possible. Can be thought of as partitioning vertices into three sets, and maximizing the number of edges between the sets. …
Grötzsch's theorem - Wikipedia
In the mathematical field of graph theory, Grötzsch's theorem is the statement that every triangle-free planar graph can be colored with only three colors. According to the four-color theorem, …
We will show how you can construct a zero-knowledge proof for Graph 3- Coloring, using a security assumption. Since Graph 3-Coloring is NP-complete, this will allow us to produce zero …
3-colouring of a graph (polynomial time)? - Stack Overflow
2014年11月10日 · Add 3 new vertices to your graph called red/green/blue, each connected to the other 2 but nothing else. Then for each vertex in your graph: Connect the vertex to red and …
In this paper we present a polynomial time algorithm that determines if an input graph containing no induced seven-vertex path is 3-colorable. This a rmatively answers a question posed by …
