    Mathematics

    Mathematics

    Accumulation of mathematical knowledge, matrix numerical optimization

    ...The repository organizes material across pure and applied mathematics, including calculus, linear algebra, probability, statistics, and optimization. It also extends into computational and algorithmic applications of mathematics, making it a useful reference for both academic study and practical problem-solving. The goal is to provide learners, researchers, and developers with a consolidated source of foundational and advanced mathematical concepts. By gathering a diverse set of topics into one repository, it supports continuous learning and interdisciplinary exploration. Its open source nature allows for community contributions and adaptation to different educational or research needs.

    Awesome Math

    Awesome Math

    This is the Curriculum for "How to Learn Mathematics Fast"

    This repository is a curated roadmap for learning the core mathematics used in computer science, machine learning, and data science without getting lost in unnecessary detours. It organizes topics like algebra, calculus, linear algebra, probability, and statistics into a pragmatic sequence that favors intuition and problem-solving over purely formal proofs. The materials emphasize short, high-leverage resources—video lectures, concise notes, and hands-on exercises—that help you build momentum quickly. It also suggests checkpoints and practice ideas so you can test comprehension and move forward with confidence. The structure is useful both for newcomers who want a starting plan and for practitioners filling specific gaps before tackling ML or deep learning. ...

    TSP Solver and Generator

    TSP Solver and Generator

    Generate and solve Travelling Salesman Problem tasks

    TSPSG is intended to generate and solve Travelling Salesman Problem (TSP) tasks. It uses Branch and Bound method for solving. An input is a number of cities and a matrix of city-to-city travel prices. The matrix can be populated with random values in a given range (useful for generating tasks). The result is an optimal route, its price, step-by-step matrices of solving and solving graph. The task can be saved in internal binary format and opened later.

    Opt4J

    Opt4J

    Modular Java framework for meta-heuristic optimization

    ...It contains a set of (multi-objective) optimization algorithms such as evolutionary algorithms (including SPEA2 and NSGA2), differential evolution, particle swarm optimization, and simulated annealing. The benchmarks that are included comprise ZDT, DTLZ, WFG, and the knapsack problem. The goal of Opt4J is to simplify the evolutionary optimization of user-defined problems as well as the implementation of arbitrary meta-heuristic optimization algorithms. For this purpose, Opt4J relies on a module-based implementation and offers a graphical user interface for the configuration as well as a visualization of the optimization process.

    PortOpt

    PortOpt

    A portfolio-optimizer using Markowitz(1952) mean-variance model

    ...In order to minimise the variance it internally uses QuadProg++, a library that implement the algorithm of Goldfarb and Idnani for the solution of a (convex) Quadratic Programming problem by means of an active-set dual method. This solution is very efficient as it allows to solve hundred of thousand of portfolio problems in seconds. PortOpt runs as a text/console tool so it can be easily used in your own scripts.

    xorlisp

    Bit level lambda continuations and nothing else - Queue automata

    Not working yet. To deal with the Halting Problem, computing and data are navigated using debugger ops: linearForward and treeForward, which navigate an astronomically large bit string where 1 is ( and 0 is ). All pairs are derived from (). For example, true is represented as ((()())()), and false is (()(()())). It appears related to the church encoding of lambda where T chooses first parameter and F chooses second, of a pair.

    ExactCalc

    Software for exact computing based on interval arithmetic.

    ...Computation can be arbitrary long and complex but interval arithmetic gives interval that contains exact result of computation. Sometimes is more easy to use numerical unstable algorithm to solve problem. Instability is actually speed of accumulating the truncation error, but it can be decreased arbitrary by using more precise computation. Interval arithmetic provides us control of accumulating truncating error. To save Your time using CPU time this program provides interpreter of simple programming language based on interval algebra with arbitrary precision arithmetic.

    datadensityplot

    Creates a data density plot of a 2 dimensional data distribution.

    Shows the data density of a 2 dimensional distribution. The problem of showing data density visually is not mathematically well defined, and there are several methods. The program uses sum of reciprocal squared distance to calculate density at each point, with a smear factor to prevent points going to infinity. The smear factor also controls the amount of clustering. There are several options for colour output.

    LIME

    LIME is a software tool for creating multiphysics simulation codes.

    ...LIME is intended to be especially useful when separate computer codes (which may be written in any standard computer language) already exist to solve di fferent parts of a multiphysics problem. LIME provides the key high-level software (written in C++), a well defi ned approach (with example templates), and interface requirements to enable the assembly of multiple physics codes into a single coupled-physics simulation code. To achieve its flexible lightweight design objectives, LIME 1.0 requires that some amount of customized software be written each time a new multiphysics application is created. ...

    ViennaFEM

    A finite element solver using state-of-the-art programming techniques.

    ViennaFEM is a library-centric implementation of the finite element method in C++. It features a symbolic math kernel, which manipulates the strong or weak form of the problem and automatically derives the discrete form. ViennaFEM is built on top of the following libraries: ViennaMath provides the symbolic math kernel, ViennaGrid (with ViennaData) allows for a generic grid handling and quantity storage, while ViennaCL provides the linear solvers and GPU acceleration.
