formulacalculator

A customizable calculator api written in java to evaluate/calculate any kind of rules or mathematical statement with functions and variables.

formulajme

Racing game developed in J2ME used as a final exam on UFRJ Computer Science course.

Chess Rating Management System

This sofware is designed to help different chess clubs to set up their own rating system. It uses USCF approximation formulas for rating calculations. Working example at newarkcc.vfutbole.ru

notecalc

Калькулятор для тех, кому нужно считать много, быстро и точно.

uniquation

Formulae editor.

Abacus Formula Compiler for Java (AFC)

Compile parametrized spreadsheets directly to bytecode. No need to have Excel, OpenOffice.org, or a JDK installed. Native speed, thread safe execution. Bind directly to your computation strategy interfaces. Using double, or BigDecimal for financial applications. Available under the GPL and ... [More] commercially. See http://formulacompiler.org/ for details. [Less]

nametoformula

An attempt at a PHP class to convert the names of elements and compounds to the correct, corresponding chemical formulas.

constraints-solver-over-r

C++ library for solving systems of linear constraints: inequalities equality and disequality. Current version is based on Fourier-Motzkin (FM) elimination for inequalities and Gaussian elimination for equality. Quantifiers “Forall” and “Exists” are allowed. Boolean connectivities ... [More] '&' -and, '|' - or '~' - not. '' '>=' '=' - arithmetical inequalities. The simplest formula for the solver might be: Exists x (x > 0 & x < 3);The solver simplifies such formula to 'true'. The solver simplifies system of equalities using LU decomposition. For example: x + y = 3 & x - y = 1 ;Gives: x = 2 & y = 1Appliances: Such solver may be applied as arithmetic online solver for software/hardware static verification tools. Solution of the linear programming problem. But since the FM algorithm is more general solver is not such efficient as a simplex method solver. Note. By now the code base is incomplete. It contains all Calculator's code and only small part of the Solver code. Rest of the code is coming. Stay tuned :) If you have questions feel free to contact me vitaly.german gmail.com [Less]

mathtextrecognizer

MathTextRecognizer2 Project Home PageThis project is being developed as the final year project of Luis Román Gutiérrez, student at the University of Seville, Spain. Its aim is to create an OCR system useful to get scientific texts in image format, including formulas, and transform them in laTeX ... [More] or MathML source code. The project consists in a program used to learn about the simbols which will be recognized, and other program which uses the databases created by the previous one to perform the actual recognition of the formulas, keeping their mathematical meaning. The plataform the project is being developed on is Mono, and the programing language C#. You can get more info in the project's WikiHome. SectionsMathTextRecognizer2 project info Origins Ideas [Less]
