The Jonker-Volgenant algorithm is much faster than the famous Hungarian algorithm for the Linear Assignment Problem (LAP). This Matlab implementation is modified from the original C++ code made by Roy Jonker, one of the inventors of the algorithm. It is about 10 times faster than the munkres code (v2.2) of the author. It can solve a 1000 x 1000 problem in about 3 seconds in a normal Intel Centrino processor.
V1.1 returns the dual...
With this package, I provide some MATLAB-functions regarding the rectangular assignment problem. This problem appears for example in tracking applications, where one has M existing tracks and N new measurements. For each possible assignment, a...
Functions related to the assignment problem. Main functions: hungarian - calculate a solution of the square assignment problem. See HELP for a reference.
Munkres algorithm (also known as Hungarian algorithm) is an efficient algorithm to solve the assignment problem in polynomial-time. The algorithm has many applications in combinatorial optimization, for example in Traveling Salesman problem.
"Hungarian algorithm" to solve the square assignment problem (original & pure MATLAB implementation). The Hungarian algorithm can also be used as a sub-solver in a B&B solver for the travelling salesman problem.

This demonstration shows the single steps of nearest neighbour, hungarian method (munkres algorithm) for assignment problem, branch and bound for symetric cost matrices. The tree of the branch and bound algorithm is shown and the user can select...
The two-step noise reduction (TSNR) technique removes the annoying reverberation effect while maintaining the benefits of the decision-directed approach. However, classic short-time noise reduction techniques, including TSNR, introduce harmonic...

A problem from Dynamics of Structures - Anil K. Chopra is picked and code written to solve the problem.The problem is to get the dynamic response of a structure using Newmark's method. System is a linear system.
In FDTD method we are truncated the problem space.But in truncating we face the problem of reflection in its boundary.The absorbing boundary condition(ABC)but its quite difficult to make 2D ABC and make use in FDTD method. This problem is...
This kind of problem arises in statistics, linear algebra, and regularization.
The method uses quadratic eigen-value problem (QEP).

We solve a binary distillation problem using the solution of a Riccati equation. We find that four plates are needed to achieve the desired product purity. We also compute the number of stages with the classical approach by stepping off stages...
In the present program three methods are used to solve a heat conduction problem. This problem is given in M. N. doOCozisik, Heat Conduction, Wiley, New York, 1980. We use pdepe, short times solution based on analytical inversion of a Laplace...
