Interfaces

This component provides supplementary features to the ones present in <random> that are specific to cxxomfort.

• Generators - A selection of PRNG generator specializations supplementing the linear_conguential_engine in the Standard Library.
• cxxomfort::library::random::splitmix64 - 64-bit simple PRNG by Sebastiano Vigna.
• default_random_engine() , from Fundamentals v2.
• reseed() , from Fundamentals v2.
• randint() , from Fundamentals v2.

All interfaces are defined in the namespace cxxomfort::library::random::.

Generators

The following linear congruential alternatives to std::minstd are provided in namespace cxxomfort::library::random :

• lcg_numerical_recipes_rand - LCG as per "Numerical Recipes"
• mmix_rand - LCG as per Donald Knuth in "The Art of Computer Programming"
• musl_rand - LCG as used by musl library's rand .
• xkcd221_rand - LCG as per Randal Munroe in "xkcd #221".
