28 May 2013 TSPSEARCH Heuristic method for the Traveling Salesman Problem (TSP) Author: Jonas Lundgren

Best TSP engine on FE - much better than Yonathan Nativ's FE#24857 (which is now my second best).

28 May 2013 another TSP solver a simple TSP local minimum solution. code is very short and simple. Author: Yonathan Nativ

Seems to be working fine for me - better than all other codes from the File Exchange both in terms of efficiency of the solution and in terms of running time. Well done!

24 May 2013 Solving Symmetrical and DisSymmetrical TSP base on Ant Colony Algorithm Using Ant Colony Optimization Algorithm to solve Traveling Salesman Problem Author: wang h

It's very slow even with 22 nodes and the results can be pretty inefficient. Maybe the author could try to improve the performance from both points of view of speed and efficiency.

24 May 2013 Ant Colony Optimization Techniques applied on Travelling Salesman Problem This program applies the typical ant colony optimization technique on TSP problem. Author: Hamid Behravan

This is a script with no comments on how to use it.

The file AS_TSP.m clears all variables (!) and then calls the file DistanceMatrix.m which contains a graph. It makes use of the function randint (from Communications Toolbox?).

I think the author should consider to rewrite it as it might be actually useful but it's not very usable in the current version.

30 Nov 2012 Analytical solution for Orthogonal Linear Least Squares in two dimensions The function returns the Orthogonal Linear Least Squares estimate for parameters of line ax+by+c=0 Author: Francesco Pozzi ln

06 Jun 2012 Inequality Package Inequality Metrics: Gini Coefficient associated to the Lorenz Curve, Theil and Atkinson indexes Author: Francesco Pozzi Pozzi, Francesco

@Martin, thank you for your comment but check it again: the Gini coefficient of your example IS NOT zero but some random number.

@Robert, thank you for your comment - I would use random data or the GDP and Population of a selection of countries.

16 May 2012 Inequality Package Inequality Metrics: Gini Coefficient associated to the Lorenz Curve, Theil and Atkinson indexes Author: Francesco Pozzi Root, Robert

Excited to find this package. I'd like to use it in my courses. Where can I find actual data in the format this package accepts?
31 Jan 2012 Rankings Calculate Rankings with five different methodologies Author: Francesco Pozzi Daniel

You might like my tiedrank_(X,dim) function: http://www.mathworks.com/matlabcentral/fileexchange/34560-tiedrankxdim
The code is fully vectorised and runs pretty fast.
