WebFeb 20, 2024 · Graph coloring refers to the problem of coloring vertices of a graph in such a way that no two adjacent vertices have the same color. This is also called the vertex coloring problem. If coloring is done using at most k colors, it is called k-coloring. The smallest number of colors required for coloring graph is called its chromatic number. WebWigderson Algorithm is a graph colouring algorithm to color any n-vertex 3-colorable graph with O(√n) colors, and more generally to color any k-colorable graph.

WebThe space complexity of M is the function f: N → N, where f (n) is the maximum number of cells of tape and M scans any input of length M. If the space complexity of M is f (n), we can say that M runs in space f (n). We estimate the space complexity of Turing machine by using asymptotic notation. Let f: N → R + be a function.
