This aims to supply a Borland Delphi translation of Alan Miller's Random Module for FORTRAN-90. This translation has been done with Dr Miller's approval and is being made FREELY available to all Delphi Developers, though we do ask the Alan Miller and ESB Consultancy be given due credit. It includes the following Random Number Generators: - Normal (Gaussian) - Gamma - Chi-squared - Exponential - Weibull - Beta - t - Multivariate Normal - Generalized inverse Gaussian - Binomial (2 different ones) - Negative Binomial - von Mises - Cauchy Includes full Delphi Source and Demo.

Expression builder 1.31 is a set of eight components - TExprFunctions, TFnCategoryCombo, TFnCategoryList, TFnListBox, TVarListBox, TUserDataListBox, TExprBuilderDlg, TExprSolver, which helps you to make a custom expression builder dialogs in your applications, to enable the user to speed entering syntax valid expressions, checks them, and stores in a dataset along with any user data.
TExprSolver helps you to evaluate stored expressions, it automatically fetches the values for all used in a given expression variables from an INI file and/or dataset.
Full help and demo included.
It needs Expression parser 3.1 to be installed.

[ D4 ]
Genetic Programming is a relatively new field of AI/ Evolutionary Computation. This component is designed to simplify implemntation of a GP System, handling all the GP-specific tasks for the user and up to this date It's probably the only one of it's kind outthere.All the user has to do is to write it's own specific fitness-evaluation function and an interface to it's system. Sources for the GP component are not included in this version, but sources for a minimal GP system are. The application included to demonstrate the component's capabilities, Boolean Multiplexer application, is a GP System by itself and has sources included.
Please let me know of any thoughts you have regarding this.

Probabilities package is a selection of probabilities functions: PDF, CDF and Inverse CDF for 19 different distributions (binomial, geometric, hypergeometric, negative binomial, Poisson, discrete uniform , beta, Cauchy, chi-squared, exponential, F, gamma, Maxwell, normal, Pareto, Rayleigh, Student (T), Continuous uniform, Weibull....) This code had been taken from MtxVec 1.02 and does not require any dll's, but also does not offer any vector processing acceleration routines. The package also includes a Math unit, which can serve as a replacement for default Delphi Math unit. Next to many basic math functions it also offers complete support for complex numbers. [more]

This is a new version of TSP Solver that was revised, redesigned and some bugs were fixed. TSP Solver is a program that solves the famous Travelling Salesman Problem (TSP) of the graph theory. It gives you the option of using the Heuristic or the Exhaustive algorithm, it calculates the optimal cost and measures the time and the flop of the algorithm. It also creates graphs of the results that are very usefull for the study of the problem and that can be saved as Bitmaps or copied to clipboard. The source of the project and the EXE file are included. No external component or package required! Includes a useful html document that explains what the TSP is.
