Assignment problem
The assignment problem is a fundamental combinatorial optimization problem. In its most general form, the problem is as follows: The problem instance has a number of agents and a number of tasks. Any agent can be assigned to perform any task, incurring some cost that may vary depending on the agent-task assignment.
Hungarian Algorithm for Assignment Problem
The Quadratic Assignment Problem (QAP) is an optimization problem that deals with assigning a set of facilities to a set of locations, considering the pairwise distances and flows between them. The problem is to find the assignment that minimizes the total cost or distance, taking into account both the distances and the flows. The distance matrix a

How well can we do with this variable assignment problem?
My motivation for tackling this particular problem is that its solution may help improve the bounds of #3-SAT by some small degree. However, the relation between the two is fairly complicated. ds.algorithms
Assignment Problems
Assignment problems deal with the question of how to assign other items (machines, tasks). There are different ways in mathematics to describe an assignment: we can view an assignment as a bijective mapping φ between two finite sets . We can write a permutation φ as 12…nφ (1)φ (2)…φ (n), which means that 1 is mapped to φ (1), 2 is ...

Assignment problems: A golden anniversary survey
Abstract. Having reached the 50th (golden) anniversary of the publication of Kuhn's seminal article on the solution of the classic assignment problem, it seems useful to take a look at the variety of models to which it has given birth. This paper is a limited survey of what appear to be the most useful of the variations of the assignment ...
Quadratic assignment problem

Usually weight and distance functions are viewed as square ...
Assignment problem with multiple workers for each job
This problem is a special case of the b-matching problem, and hence can be solved in polynomial time. Extensive information on b-matchings can be found for instance in the book: László Lovász and Michael D. Plummer: Matching Theory ISBN-10: -8218-4759-7 ISBN-13: 978--8218-4759-6

Data Structures and Algorithms (DSA) refer to the study of methods for organizing and storing data and the design of procedures (algorithms) for solving problems, which operate on these data structures. DSA is one of the most important skills that every computer science student must have. It is often seen that people with good knowledge of these technologies are better programmers than others ...
PDF 17 The Assignment Problem
Exercise 17 shows that the number of iterations is O(n2). To compare the Hungarian method to the exhaustive search method mentioned above, suppose that each iteration can be performed in one second. Then an assignment prob-lem with n = 30 can be solved in at most 302 = 900 seconds, or 15 minutes of computer time.
Introduction to Data Structures
A data structure is a particular way of organising data in a computer so that it can be used effectively. The idea is to reduce the space and time complexities of different tasks. The choice of a good data structure makes it possible to perform a variety of critical operations effectively. An efficient data structure also uses minimum memory ...
Data Structures and Algorithms Tutorial
A problem can be solved using various approaches, but you have to pick the optimized one in order to be more productive and solve the problem in lesser time. It can be done through learning data structures and algorithms. The core of computer science - Data structures and algorithms are considered to be the foundation of computer science. With ...
Operations Research with R
The assignment problem represents a special case of linear programming problem used for allocating resources (mostly workforce) in an optimal way; it is a highly useful tool for operation and project managers for optimizing costs. The lpSolve R package allows us to solve LP assignment problems with just very few lines of code.

Stack Data Structure
A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle. It behaves like a stack of plates, where the last plate added is the first one to be removed. Think of it this way: Pushing an element onto the stack is like adding a new plate on top. Popping an element removes the top plate from the stack.
A Comparative Analysis of Assignment Problem

What is Task Assignment Approach in Distributed System?
As the name implies, the task assignment approach is based on the division of the process into multiple tasks. These tasks are assigned to appropriate processors to improve performance and efficiency. This approach has a major setback in that it needs prior knowledge about the features of all the participating processes.
