Greedy and dynamic approach

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. WebNov 4, 2024 · Dynamic programming requires more memory as it stores the solution of each and every possible sub problems in the table. It does lot of work compared to greedy approach, but optimal solution is ensured. In following table, we have compared dynamic programming and greedy approach on various parameters.

WebA greedy algorithm is an approach for solving a problem by selecting the best option available at the moment. It doesn't worry whether the current best result will bring the overall optimal result. The algorithm never reverses the earlier decision even if the choice is wrong. It works in a top-down approach. This algorithm may not produce the ...
