dqrng (unreleased)
- Make template specialisations
inline and include required standard headers (Aaron Lun in #29 fixing #28)
- Add workaraound for new C++ compiler with old libc (#30 fixing #27)
- update maintainer’s email address
dqrng 0.2.0
- Add R side support for selecting multiple streams for parallel usage.
- Implement
long_jump() for Xo(ro)shiro as alternative to jump() providing fewer streams with longer period.
- Handle R’s RNG scope properly during initialisation.
- New functions
dqsample and dqsample.int using an unbiased sampling algorithm.
- Use
R_unif_index() instead of unif_rand() to retrieve random data from R’s RNG in generateSeedVectors().
- Scalar RNGs in the C++ API: dqrng::runif, dqrng::rnorm and dqrng::rexp
dqrng 0.1.1
- Use template specializations to avoid compiler warnings during tests (Aaron Lun in #16)
- Do not expect a particular error message on MacOS and skip exception throwing tests on Solaris.
dqrng 0.1.0
Breaking changes
- An integer vector instead of a single
int is used for seeding (Aaron Lun in #10)
- Single integer seeds lead to a different RNG state than before.
dqrng::dqset_seed() expects a Rcpp::IntegerVector instead of an int
- Support for Mersenne-Twister has been removed, Xoroshiro128+ is now the default.
Other changes
- New method
generateSeedVectors() for generating a list of random int vectors from R’s RNG. These vectors can be used as seed (Aaron Lun in #10).
- The initial state of the default RNG is now based on R’s RNG.
dqrng 0.0.5
- New RNG: Threefry from package ‘sitmo’
- Update PCG Headers (c.f. #8)
- Unit-Tests for the C++ interface
- Define STRICT_R_HEADERS to prepare for future Rcpp (c.f. #6)
dqrng 0.0.4
- Fix critical bug w.r.t. setting seeds
- Use time in addition to
std::random_device as source of the default seed, since std::random_device is deterministic with MinGW (c.f. #2)
- Add jump() method to Xoshiro256+ and Xorohiro128+
- New vignette on parallel usage
dqrng 0.0.3
- PCG has been patched to compile on Solaris.
dqrng 0.0.2
dqrng_distribution.h can now be used independently of Rcpp- Replace
xorshift.hpp and xoroshiro.hpp with xoshiro.h. This implementation is directly derived from the original C implementations. It provides v1.0 of Xoroshiro128+ and Xoshiro256+.
