Greedy algorithm ppt
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. WebOct 7, 2014 · Greedy Algorithms • Optimization problems minimize or maximize some parameter over all possible inputs. For instance, we can refer to: • Finding a route between two cities with the smallest total mileage. • Finding the fiber links among nodes using the least amount of fiber.
