RcppBigIntAlgos 1.1.0 (2023-08-16)

• Migrated from Rcpp to cpp11
• Fixed C++ requirements per new CRAN policy
• Added github actions
• Dropped RcppThread in favor of the standard library

RcppBigIntAlgos 1.0.1 (2021-01-08)

• Fixed showStats option for smaller numbers

RcppBigIntAlgos 1.0.0 (2020-12-12)

• Added generalized prime factorization function 'primeFactorizeBig' which now can utilize the elliptic curve method.
• Slightly changed the interface to be more consistent.

RcppBigIntAlgos 0.3.5

• Improved divisibility checking and data locality for greater efficiency.

RcppBigIntAlgos 0.3.4 (2020-11-04)

• Improved sieving and tuning for greater efficiency.

RcppBigIntAlgos 0.3.3 (2020-10-13)

• Now using bitset for more efficient linear algebra.
• Also fixed additional memory issues. Confirmed fix by running rhub::check_with_sanitizers(), rhub::check_with_valgrind(), as well as running custom docker clang-ASAN.

RcppBigIntAlgos 0.3.2

• Fixed ASAN/UBSAN/valgrind issue. See https://github.com/jwood000/RcppBigIntAlgos/issues/1 for more information.

RcppBigIntAlgos 0.3.1 (2020-09-28)

• Fixed URL in README

RcppBigIntAlgos 0.3.0

• Multiple threads can now be used.
• Switched completely to gmpxx. Had to copy gmpxx source and modify in order to easily build on all platforms.

RcppBigIntAlgos 0.2.5

• Improved efficiency of quadraticSieve by segmenting the sieving portion. For larger number (greater than 65 decimal digits) it has a great impact.

RcppBigIntAlgos 0.2.4 (2020-06-22)

• Fixed link in documentation in accordance with the new policy in Writing R Extensions (section: Cross-references)

RcppBigIntAlgos 0.2.3

• Replaced array of precalculated interval values by only calculating interval values that meet the threshold. This greatly improves efficiency.
• Refactored portions of the algorithm in preparation for parallel computing.
• Improved helper algorithm (i.e. sieveLists in SieveUtils.cc)

RcppBigIntAlgos 0.2.2 (2020-04-23)

• Added "Free Software Foundation, Inc." as copy right holder in DESCRIPTION
• Adjusted sieving factors for improved efficiency, especially on numbers with greater than 50 digits
• Improved efficiency by utilizing more light weight data structures
• Added safety measures to ensure mpz_t arrays don't overflow

RcppBigIntAlgos 0.2.1

• Added references in DESCRIPTION file
• Added Mike Tryczak as contributor
• One can now see summary statistics via the showStats parameter in the quadraticSieve function

RcppBigIntAlgos 0.2.0

• Now uses Rcpp & RcppThread (Multiple threads are not enabled yet, but will be the focus of the next major release)
• Changed the package name to be more in line with the related RcppAlgos package
• Major overhaul of quadratic sieve algorithm
• You can now safely interrupt execution
• Removed config files and classes associated with the gmp R library
• Now uses C++11
• quadraticSieve now accepts negative numbers. It behaves similarly to gmp::factorize

RcppBigIntAlgos 0.1.2

• Fixed additional error found on Solaris flavor in quadraticsieve.cc

RcppBigIntAlgos 0.1.1

• Fixed error associated with the Solaris flavor in factorization.cc file.
• Forced complilation with C++11 on Windows build only (see Makevars.win) to address the following warnings : "ISO C++ 1998 does not support 'long long' [-Wlong-long]"
• Slightly altered factors that determine the cutoff point for sieving the log sum of the prime decomposition of the sieving interval constituents

RcppBigIntAlgos 0.1.0

• Initial Release
