WebThe FastDP algorithm [ Pan 2005] is a greedy heuristic that can generate slightly better solutions than Domino and is an order of magnitude faster. The FastDP algorithm consists of four key techniques: global swap, vertical swap, local reordering, and single-segment clustering. The flow of FastDP is given in Algorithm 11.3. Algorithm 11.3 WebGreedy can be tricky Our greedy solution used the activity with the earliest finish time from all those activities that did not conflict with the activities already chosen. Other greedy approaches may not give optimum solutions to the problem, so we have to be clever in our choice of greedy strategy and prove that we get the optimum solution.
