{ "_id": "6a10189dacfb0bcc41c85883", "Package": "RcppAlgos", "Version": "2.10.0", "Title": "High Performance Tools for Combinatorics and Computational\nMathematics", "Description": "Provides optimized functions and flexible iterators\nimplemented in C++ for solving problems in combinatorics and\ncomputational mathematics. Handles various combinatorial\nobjects including combinations, permutations, integer\npartitions and compositions, Cartesian products, unordered\nCartesian products, and partition of groups. Utilizes the\nRMatrix class from 'RcppParallel' for thread safety. The\ncombination and permutation functions contain constraint\nparameters that allow for generation of all results of a vector\nmeeting specific criteria (e.g. finding all combinations such\nthat the sum is between two bounds). Capable of\nranking/unranking combinatorial objects efficiently (e.g.\nretrieve only the nth lexicographical result) which sets up\nnicely for parallelization as well as random sampling. Gmp\nsupport permits exploration where the total number of results\nis large (e.g. comboSample(10000, 500, n = 4)). Additionally,\nthere are several high performance number theoretic functions\nthat are useful for problems common in computational\nmathematics. Some of these functions make use of the fast\ninteger division library 'libdivide'. The primeSieve function\nis based on the segmented sieve of Eratosthenes implementation\nby Kim Walisch. It is also efficient for large numbers by using\nthe cache friendly improvements originally developed by Tomás\nOliveira. Finally, there is a prime counting function that\nimplements Legendre's formula based on the work of Kim Walisch.", "URL":
