PDL::MatrixOps Perl module contains some useful Matrix operations. SYNOPSIS $inv = $a->inv; $det = $a->det; ($lu,$perm,$par) = $a->lu_decomp; $x = lu_backsub($lu,$perm,$b); # solve $a x $x = $b PDL::MatrixOps is PDLs built-in matrix manipulation code. It contains utilities for many... Platforms: *nix

Algorithm::DiffOld is a Perl module to compute `intelligent differences between two files / lists but use the old (<=0.59) interface. NOTE This has been provided as part of the Algorithm::Diff package by Ned Konz. This particular module is ONLY for people who HAVE to have the old interface,... Platforms: *nix

Algorithm::BinPack is a Perl module that can efficiently pack items into bins. SYNOPSIS Algorithm::BinPack efficiently packs items into bins. The bins are given a maximum size, and items are packed in with as little empty space as possible. An example use would be backing up files to CD,... Platforms: *nix

Algorithm::Permute is a Perl module with handy and fast permutation with object oriented interface. SYNOPSIS use Algorithm::Permute; my $p = new Algorithm::Permute([a..d]); while (@res = $p->next) { print join(", ", @res), "n"; } my @array = (1..9); Algorithm::Permute::permute { print... Platforms: *nix

Algorithm::Huffman is a Perl extension that implements the Huffman algorithm. SYNOPSIS use Algorithm::Huffman; my %char_counting = map {$_ => int rand(100)} (a .. z, A .. Z); # or better the real counting for your characters # as the huffman algorithm doesnt work good with random data... Platforms: *nix

Algorithm::Networksort can create inline comparisons for sorting. SYNOPSIS use Algorithm::Networksort qw(:all); my $inputs = 4; # # Generate the network (a list of comparators). # my @network = nw_comparators($inputs); # # Print the list, and print the graph of the list. # print... Platforms: *nix

Algorithm::Line::Bresenham is a Perl module that contains a simple pixellated line-drawing algorithm. SYNOPSIS use Algorithm::Line::Bresenham qw/line/; my @points = line(3,3 => 5,0); # returns the list: [3,3], [4,2], [4,1], [5,0] line(3,3 => 5,0, &draw_line); # calls draw_line on each... Platforms: *nix

Algorithm::NeedlemanWunsch is a sequence alignment with configurable scoring. SYNOPSIS use Algorithm::NeedlemanWunsch; sub score_sub { if (!@_) { return -2; # gap penalty } return ($_[0] eq $_[1]) ? 1 : -1; } my $matcher = Algorithm::NeedlemanWunsch->new(&score_sub); my $score =... Platforms: *nix

This is an implementation of the binary search algorithm in (almost) one line. Given a number 'n' and a list 'L', the function returns the index of the number on the list, or -1. Platforms: Windows, Mac, *nix, Python, BSD Solaris

NSGA-II is a very famous multi-objective optimization algorithm. I submitted an example previously and wanted to make this submission useful to others by creating it as a function. Even though this function is very specific to benchmark problems, with a little bit more modification this can be... Platforms: Matlab

This software contains one example taken from the reference paper given with this program..By running the file P1.m as they are in the default ABC-eld folder the economic dispatch problem can be solved. The allocation minimum fuel cost and transmission losses are determined. By running the... Platforms: Matlab

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... Platforms: Matlab

findMIS is an heuristic algorithm for solving Maximum Independent Set problem (MIS).An independent set of a graph is a subset of vertices in which no two vertices areadjacent. Given a set of vertices, the maximum independent set problem callsfor finding the independent set of maximum... Platforms: Matlab

In this M-file, the implementation of ACO Algorithm is given with the support of reference papers listed. You can easily use it as following command to see the pictures of result and the playing iterative course.ACO('filename.tsp');filename.tsp is the problem file of the Symmetrical or...

SpeedyGA is a vectorized implementation of a genetic algorithm in the Matlab programming language. Without bells and whistles, it faithfully implements the specification for a Simple GA given on pgs 10, 11 of M. Mitchell's GA book. See comments in code for details.This script has played a crucial... Platforms: Matlab

The Matlab convhulln is a gateway to the quickhull algorithm ( see www.qhull.org ). In my opinion, one weak point of this mex routine is that it processes all the points without performing any preliminary filtering.In many cases it would be faster if only the point that can be part of the...
