WebGreedy Algorithm- Step-01: Color first vertex with the first color. Step-02: Now, consider the remaining (V-1) vertices one by one and do the following- Color the currently picked vertex with the lowest numbered color if it has not been used to color any of its adjacent vertices. If it has been used, then choose the next least numbered color.

WebApr 13, 2024 · Background The expectation maximization (EM) algorithm is a common tool for estimating the parameters of Gaussian mixture models (GMM). However, it is highly sensitive to initial value and easily gets trapped in a local optimum.
