WebLongest-processing-time-first (LPT) is a greedy algorithm for job scheduling.The input to the algorithm is a set of jobs, each of which has a specific processing-time.There is also a number m specifying the number of machines that can process the jobs. The LPT algorithm works as follows: Order the jobs by descending order of their processing … WebGreedy Algorithm- Greedy Algorithm is adopted to determine how the next job is selected for an optimal solution. The greedy algorithm described below always gives an optimal solution to the job sequencing problem- Step-01: Sort all the given jobs in decreasing order of their profit. Step-02: Check the value of maximum deadline.
