...This project isn't limited to GLSL features. An extension system, based on the GLSL extension conventions, provides extended capabilities: matrix transformations, quaternions, data packing, random numbers, noise, etc. This library works perfectly with OpenGL but it also ensures interoperability with other third party libraries and SDK. It is a good candidate for software rendering (raytracing / rasterisation), image processing, physics simulations and any development context that requires a simple and convenient mathematics library. ...

Google Optimization Tools, also known as OR-Tools is an open-source, fast and portable software suite for solving combinatorial optimization problems. These encompass problems in vehicle routing, flows, integer and linear programming, and constraint programming. This suite contains a number of solvers, namely: a constraint programming solver; a linear programming solver; wrappers for commercial solvers (like Gurobi or CPLEX) and other open source solvers (SCIP, GLPK, etc.); among others....

Estimates the maximum random close packing fraction of hard spheres with a distribution of diameters, based upon an algorithm in J. Chem. Phys. 131, 244104 (2009).

popt4jlib is an open-source parallel optimization library for the Java programming language supporting both shared memory and distributed message passing models. Implements a number of meta-heuristic algorithms for Non-Linear Programming, including Genetic Algorithms, Differential Evolution, Evolutionary Algorithms, Simulated Annealing, Particle Swarm Optimization, Firefly Algorithm, Monte-Carlo Search, Local Search algorithms, Gradient-Descent-based algorithms, as well as some well-known...

...The project originated from the LIGGGHTS ecosystem and has been used in combination with CFDEM coupling workflows for particle-fluid simulations. It helps users study mechanical contact, particle motion, collision behavior, packing, flow, and equipment-scale granular processes. The software is especially relevant for engineering applications where macroscopic behavior emerges from many particle-level interactions. Its main value is providing a DEM simulation engine for researchers and engineers who need detailed particle-scale modeling in open-source workflows.

Maximum packing densities for individual, polydisperse (diameter), ellipitic platelets and stacks of them (max 5 platelets per stack implemented). Size fractionating for stacks (platelets with diameters below a cut-off diameter remain as individual platelets all others assemble in stacks) can be included. Considers only hard interactions and assumes spherical exclusion volumes.

It uses two different solutions: - placing of circles closest to the center from the largest to smallest, see brianshaler on github https://github.com/brianshaler/Circle-Packing-in-Processing - simulation "real" world with use of a Java Physics Engine JBox2D, see http://www.jbox2d.org

Software to identify cavities and crevices in proteins. The goal is to be able to take a protein structure, and to differentiate between five different types of environments for each residue: buried, surface, interfacial, cavity, or crevice.

A disk based production quality RTree based upon Guttman’s quadratic split algorithm having following features: Buffering with dirty write, Index joins, Tree Seeding, Window and NN queries, Runtime STR Packing capability, Completely Thread safe.

JOrigami is a collection of algorithms for computational origami. Some algorithms studied by computational origami does not have an implementation. JOrigami solves the famous and funny fold-and-cut using Demaine's disk packing implementation.
