js-combinatorics - power set, combination, permutation and more in JavaScript

•    Javascript

---

Combinatorics is now available in your app/package namespace. All methods create generators. Instead of creating all elements at once, each element is created on demand. So it is memory efficient even when you need to iterate through millions of elements.

streamplify - Java 8 combinatorics-related streams and other utilities

•    Java

---

The goal of this library is to provide useful Java 8 streams and to assist you in building new streams that allow efficient parallel processing.The following code snippet uses a parallel permutation stream to find all solutions of the N-Queens problem for n = 10.

n-pair - generate pairings for n-many sets

•    Javascript

---

Pair each array in the array sets together in all the possible combinations, calling cb(pairing) with each possible pairing.

resamplr - R package cross-validation, bootstrap, permutation, and rolling window resampling techniques for the tidyverse

•    R

---

The resamplr package provides functions that implement resampling methods including the bootstrap, jackknife, random test/train sets, k-fold cross-validation, leave-one-out and leave-p-out cross-validation, time-series cross validation, time-series k-fold cross validation, permutations, rolling windows. These functions generate data frames with resample objects that work with the modelling pipeline of modelr and the tidyverse. The resamplr package includes functions to generate data frames of lazy resample objects, as introduced in the tidyverse modelr package. The resample class stores the a "pointer" to the original dataset and a vector of row indices. The object can be coerced to a dataframe with as.data.frame and the row indices with as.integer.

generatorics - An efficient combinatorics library for JavaScript utilizing ES2015 generators.

•    Javascript

---

Note: This module is not transpiled for compatibility, as it degrades the performance. Check your browser/node version. For efficiency, each array being yielded is the same one being mutated on each iteration. DO NOT mutate the array.

golang-combinations - Golang library which provide an algorithm to generate all combinations out of a given string array

•    Go

---

This package provides a method to generate all ordered combinations out of a given string array. This essentially creates the powerset of the given array except that the empty set is disregarded. Take a look at the godoc for examples.

permute - Restricted permutations

•    R

---

permute generates permutations from a range of restricted permutation designs. Permute provides an R implementation of the permutation schemes developed by Cajo ter Braak and made available in the Canoco software, version 3.1 (ter Braak, 1990). These permutation schemes draw upon ideas from an earlier paper by Besag & Clifford (1989).
