Detailed Description

Generic thread-safe generator of pseudo-random number generators.

To use, call the static member get() to get a pseudo-random number generator seeded with an initial pseudo-random value.

Implementation internally uses a mutex, so that this generator can be safely called concurrently from multiple threads. The initial seed used is the number of microseconds elapsed since 01/01/1970, cast to uint32_t.

Member Function Documentation

template<class Rng >

template rng_uint32 pagmo::rng_generator::get< rng_uint32 > ( )

static

Return pseudo-random number generator.

Type Rng must be a Boost-like pseudo-random number generator initialisable with a boost::uint32_t. Return value is seeded with an internal static pagmo::rng_uint32.

Returns

pseudo-random number generator seeded with pseudo-random value.

void pagmo::rng_generator::set_seed ( int  n )

static

Set seed.

Set the seed of the internal generator to n. Thread-safe. Note that input integer n will be cast to uint32_t.

Parameters

[in]

n

seed for the generator of pseudo-random number generators.
