WebSince we need to maximize the objective function, Greedy approach can be used. Following steps are followed to find the solution: Step 1: Initialize sum = 0. Step 2: Select the root node, so its value will be added to sum, sum = 0+8 = 8. Step 3: The algorithm compares nodes at next level, selects the largest node which is 12, making the sum = 20. WebA greedy graph-coloring algorithm We present an algorithm to color the vertices of an undirected graph so that neighbors have different colors. It is an abstract algorithm, in the sense that we number the n vertices 0, 1, …, n-1 and assume we have n colors, also numbered n0, 1, …, -1.
