Following are commonly asked greedy algorithm problems in technical interviews: Activity Selection Problem Given a set of activities, along with the starting and finishing time of each activity, find the maximum number of activities performed by a single person assuming that a person can only work ...
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...
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 ...
This repository contains the solutions and explanations to the algorithm problems on LeetCode. Only medium or above are included. All are written in C++/Python and implemented by myself. The problems attempted multiple times are labelled with hyperlinks.
Dr. McCaffrey this month presents a greedy algorithm as a solution to the graph maximum clique problem, which is to find the largest group of nodes in a graph that are all connected to one another. He explains how to design and test these algorithms to solve the problem....
The whale optimization algorithm has received much attention since its introduction due to its outstanding performance. However, like other algorithms, the whale optimization algorithm still suffers from some classical problems. To address the issues of
While ABC1 focused on exploring the search space though using a probabilistic solution acceptance mechanism, ABC2 worked inside ABC1 and focused on the search around the current best solutions by using a greedy mechanism. The proposed algorithm was tested on the Moving Peak Benchmark. The ...

As a newly proposed optimization algorithm based on the social hierarchy and hunting behavior of gray wolves, grey wolf algorithm (GWO) has gradually become a popular method for solving the optimization problems in various engineering fields. In order to further improve the convergence speed, solution...
On the other hand, contains powers of , while has none. This represents the (multi-)set of primes one has to redistribute in order to convert a factorization of to a factorization of . Using a greedy algorithm, one can match a -heavy prime to each -heavy prime (counting multiplicity)...
