It is well known that the greedy algorithm minimizes \\\( \\\sumolimits_{i \\\in A} {{C_i}} \\\) subject to A ∈ ß where ß is the set of bases of a matroid and C i is the deterministic cost assigned to element i . In this paper, we consider the case that C i ar...
Problems on Algorithms by Ian Parberry & William Gasarch 268 pages | Prentice Hall; 2nd edition (2002) | English | | 2.35 MB Too often the problem sets in standard algorithm texts are composed of small, idiosyncratic units of busy-work and irrelevant questions -- forcing instructors into ...
In this article, we are going to seewhat greedy algorithm isandhow it can be used to solve major interview problems based on algorithms?Submitted byRadib Kar, on December 03, 2018 Introduction: Let's start the discussion with an example that will help to understand thegreedy technique. If ...
The greedy strategy is an approximation algorithm to solve optimization problems arising in decision making with multiple actions. How good is the greedy strategy compared to the optimal solution? In this survey, we mainly consider two classes of optimization problems where the objective function is ...

Although our methods cannot beat MD-Greedy algorithm, they do not use any prior information about the graph. However, MD-Greedy requires to compute degrees of all nodes on the graph. Furthermore, we do not report the results of GA algorithm, because without heuristic and specific design, the...

Explicit ranking of items by their value-to-weight ratios may facilitate the use of the greedy algorithm in the early stages of the search process. One of our key findings is that participants tended to spend more effort on, and hence, improved economic performance in, more difficult problems...
