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. 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.
