This module is meant to be an introduction to the internal operations of Neural Networks. It lets the user create a single node in a neural net based on the Perceptron model.

Algorithm::Combinatorics is an efficient generator of combinatorial sequences, where efficient means: * Speed: The core loops are written in C. * Memory: No recursion and no stacks are used. Tuples are generated in lexicographic order.

Algorithm::CurveFit implements a nonlinear least squares curve fitting algorithm. That means, it fits a curve of known form (sine-like, exponential, polynomial of degree n, etc.) to a given set of data points.

Algorithm::KMeans is a perl5 module for the clustering of numerical data in multidimensional spaces. Since the module is entirely in Perl (in the sense that it is not a Perl wrapper around a C library that actually does the clustering), the code in the module can easily be modified to experiment with several aspects of automatic clustering. For example, one can change the criterion used to measure the "distance" between two data points, the stopping condition for accepting final clusters, the criterion used for measuring the quality of the clustering achieved, etc.

Algorithm-Munkres is a perl extension for Munkres' solution to classical Assignment problem for square and rectangular matrices This module extends the solution of Assignment problem for square matrices to rectangular matrices by padding zeros. Thus a rectangular matrix is converted to square matrix by padding necessary zeros.

A library of generic CAD-related geometry calculations.

This distribution re-implements some, but not all, of the formulas that come with GIS::Distance in the C programming language. C code is generally much faster than the perl equivilent.

The module provides a method to calculate geographic distances between coordinates in geodetic WGS84 format using the Haversine formula. It is similar to GIS::Distance, but without the extra bells and whistles and without the additional dependencies. Same great taste, less filling. It exists for those who cannot, or prefer not to install Moose and its dependencies.

This perl library aims to provide as many tools to make it as simple as possible to calculate distances between geographic points, and anything that can be derived from that.

The Geo::Distance::XS module provides faster C implementations of the distance calculations found in Geo::Distance. See the documentation for that module for usage.
