(description
|
||||||
|
"Several fast random number generators are provided as C++ header-only
|
||||||
|
libraries: the PCG family as well as Xoroshiro128+ and Xoshiro256+.
|
||||||
|
Additionally, fast functions for generating random numbers according to a
|
||||||
|
uniform, normal and exponential distribution are included. The latter two use
|
||||||
|
the Ziggurat algorithm originally proposed by Marsaglia and Tsang. These
|
||||||
|
functions are exported to R and as a C++ interface and are enabled for use
|
||||||
|
with the default 64 bit generator from the PCG family, Xoroshiro128+ and
|
||||||
|
Xoshiro256+ as well as the 64 bit version of the 20 rounds Threefry
|
||||||
|
engine (Salmon et al., 2011) as provided by the package @code{sitmo}.")
