As reported earlier, the greedy algorithm is commonly used to solve P4S problems in the built environment domain. While it does not guarantee optimal solutions, it does commonly achieve reasonable ones. Enhancements to the greedy algorithm, e.g. using weighted greedy, backtracking or SA, have als...
The greedy algorithm is known for being efficient. It chooses the best option at each step to find the best overall outcome. But when exactly should one employ this approach?Optimal Substructure: The greedy algorithm works best for problems that can be broken down into smaller parts. Making a...

Greedy algorithmThe widely used greedy algorithm has been recently shown to achieve near-optimal theoretical guarantees for the problems of constrained monotone non-submodular function maximization, with competitive performances in practice. In this paper, we investigate the problems of maximizing monotone ...
Actual computation, often in a relatively standard way, possibly a greedy algorithm or DP. Of course, this picture is simplified. In practice, the steps are very much intertwined, and it is usually hard to write down the two phases so explicitly separately. But the general idea stays the sa...

This algorithm has been well-studied from an approximation point of view and it has been shown to have a bad worst case approximation factor. However, all the bad approximation factors presented so far stem from complicated recursive construction. In practice the greedy algorithm seems to have ...

A greedy algorithm is a very simple and efficient method for solving optimisation problems. At each step, the greedy algorithm seeks the local optimum, without regard for future consequences, in an attempt to achieve the global optimum. As an example, consider a case where we have nine jobs ...
