MongoDB Atlas runs apps anywhere
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
A declarative logic programming system with first-class relations
embedded in a pure functional subset of Scheme. The system has true
unions, fair scheduling, lexically-scoped logical variables,
set-theoretical semantics, high performance without cuts
Implementation of algorithm from paper 'Numerical Approximation of Option Premia in Displaced-Lognormal Heston Models' by A Dickinson. For code: click link under 'Develop' & checkout via svn or click link under Browse Code->SVN & download tarball
A random collection of c++ tidbits.
I write some code as I go along. Maybe this is useful to anyone. Maybe I will turn some of it into a library at some point.
But not now.
Start building on Google Cloud with $300 in free credits. No commitment, no credit card required until you're ready to scale.
Launch your next project with $300 in free Google Cloud credits—no strings attached. Test, build, and deploy without risk. Use your credits across the entire Google Cloud platform to find what works best for your needs. After your credits are used, continue with always-free tier services. Only pay when you're ready to scale. Sign up in minutes and start exploring.
libNT is a Number Theory Library which is based on a BigInteger Class. It will contain several algorithms for solving Number Theory Problems. Written in the IDE Code::Blocks
Don't hard-code data-structures for Artificial Intelligence (AI). Evolve them (and control flow) as cycles of arrays in arrays with size constraints based on other array sizes (at specific index) in terms of range, multiply, exponent, or permutation. No working code yet. Whats there now is an extension of GigaLineCompile which would become part of Human AI Net, but there are other projects to finish before I can come back to this one.
SimKernel controls parameter scans and iterations for any given C++ code / scientific simulation. Parameters, iteration ranges, settings and dependencies are specified in Mathematica syntax. Parallel processing of parameter scanning via MPI.
Foma is a compiler, programming language, and C library for constructing finite-state automata and transducers for various uses. It has specific support for many natural language processing applications such as producing morphological analyzers.
*** There is now an active effort to include a QT-only (no KDE) based IDE for Octave that is part of the main Octave source code. I recommend that you build and test that version of an IDE, as it will be the most supported option going forward. ***
The octavede is a development environment for the Octave mathematical software package. Octave normally is run in a terminal. Octavede provides an GTK/X11 application that provides functionality similar to other mathematical software packages.
1. Create an object-oriented python script that can represent mathematical concepts and their properties. 2. Represent all numeric values exactly. 3. Provide a variety of formats to export or embed representations of the mathematical concepts.
LSGTL means LLX’s Static Graph Template Library which is a light-weighted header-only template library developed mainly for static graph analysis. LSGTL is expected to be used in laboratories for research purposes mostly.
a simple software implemented FPU. only 32bit precision is supported and the operation result is not accurate as modern FPUs, but it is light and compact. (uses simple 32bit integer operations only, good for machines that has no hardware FPU.)
NT2 is a multi-platform C++ library providing various template matrix classes that can be used with a Matlab(tm) like syntax whose performances are close to those obtained with hand written C code. NT2 comes with various numerical toolboxes.
Software for graphs visualization, encouraging graph algorithms implementation. Aimed at students who want to code their own algorithms and see a graphical representation of it working.
JsMath is a means of including mathematical notation in web pages. It interprets TeX code within your document and uses JavaScript, CSS and unicode fonts to typeset the resulting formulas. It works across multiple browsers and platforms, without MathML
GeoGebra is free and multi-platform dynamic mathematics software for learning and teaching geometry, algebra, statistics, and calculus. Download the free software at http://www.geogebra.org. Find the source code at http://www.geogebra.org/trac
FPlot is a windows programm and a .NET library to plot and fit mathematical functions and data. The core concept of FPlot is that functions are entered as C# code and compiled on the fly. Thus the software is very fast and extensible.
Liberate your MATLAB code with LiberMate. Translate your software to free (libre) Python and the SciPy package. Are you a graduating student loosing access to MATLAB or an institution needing to share/collaborate scientific software with others.
A C++ utility library featuring a javascript interpreter, regular expressions, automatic arrays, garbage collection, matrix handling, planar geometry (regions etc) and other useful features. Blends well with STL code.
A platform which hosts battles between Fruit War robots - special java programs. The platform accepts source code as robot, and ranks all robots according to battle result. This project has been totally refined and is now hosted at http://robotypo.appspot.com
The Eight Queens Problem is a chess board puzzle. Eight queens can be placed on the chess board without conflict. Any queen placed on the chess board will not attack any other queen. JavaScript programming language is used.
METIL is a python-like interpreted or compiled language made for speed and generic programming, as in C++ but with static symbolic computations, type propagation, "for" surdefinition. Object orientation is centered on properties, rather than hierarchy.
JFEP is a Java fast mathematical expression parser and evaluator. It is designed to avoid inefficiency and to support multiple evaluations without overhead.
