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.

WebThere are numerous problems minimizing lateness, here we have a single resource which can only process one job at a time. Job j requires tj units of processing time and is due at time dj. if j starts at time sj it will finish at time fj=sj+tj. We define lateness L=max {0,fj-dh} for all j. The goal is to minimize the maximum lateness L. 1. 2. 3. http://www.janelia.org/
