WebAlgorithm #1: order the jobs by decreasing value of ( P [i] - T [i] ) Algorithm #2: order the jobs by decreasing value of ( P [i] / T [i] ) For simplicity we are assuming that there are no ties. Now you have two algorithms and at least one of them is wrong. Rule out the algorithm that does not do the right thing. WebBelow is the greedy algorithm that is always supposed to give an optimal solution to the job sequencing problem. Step-01: Sorting of all the given jobs in the decreasing order of their profit. Step-02: Checking the value of the maximum deadline. Drawing a Gantt chart such that the maximum time on the Gantt chart is the value of the maximum ...
WebJan 12, 2024 · Greedy algorithm: A greedy algorithm is a simple, intuitive algorithm that is used in optimization problems. The algorithm makes the optimal choice at each step as it attempts to find the overall optimal way to solve the entire problem. Prim's Algorithm. Prim's Algorithm also uses the Greedy approach to find the minimum spanning tree. Example: WebThe Greedy method is the simplest and straightforward approach. It is not an algorithm, but it is a technique. The main function of this approach is that the decision is taken on the …
