Expression Solver computes the value of a mathematical equation/expression. Works with operators, numbers, variables, and functions. Users can define their own variables and functions. hosted: http://github.com/matcatc/Expression-Solver
The Felo rating system provides an objective fencing strength estimate for each individual fencer in a group, just like the Elo rating in chess. This program calculates the Felo numbers by analysing a bout result list created by the user.
A simple little program, that can convert quaternions from a exponential form to a usual form. I will argue for this method, which I find very natural and quite intuitive.
This is a simple C# command line calculator. It evaluates arithmetic expressions and functions. Easy to extend. Features include factorials, powers, brackets, bracket normalization, polish notation, factorization, fields, and advanced error reporting.
Ariel is an implementation of the quadratic sieve in Java. Ariel is simple to use and requires minimal knowledge of the sieve's mechanisms for factorizations.
TaDaPro is a command-line utility to operate with numerical column tabulated data.
It is intended for operations that are cumbersome to do by hand in a spreadsheet, and for transformations that have to be applied as a batch process on many files.
Framework: Project for Evolutionary Predator Prey Algorithms, used to implement an evolutionary scheme based on the developement by van Laumanns. Implement testproblems, special behaviours, environments, and other yet not known features.
FElt is an open source system for finite element analysis, primarily for mechanical problems. FElt includes command line tools, an X11 interface for pre- and post-processing, and a Windows editor interface with some post-processing capabilities.
Corikon is a simple software to visualise the correlation matrix of a set of data, using the iconography of correlations.The first step of the project has been reached: rendering the distribution of data according to the user wills.
During a course at University "La Sapienza" in Rome I developed a fully working SAT solver based on unit propagation and backtracking; it can read DIMACS files and process cnf formulas of any length(there are no restrictions on the number of literals).
