Detailed Description

Pseudo-random number generator.

Based on the classic Mersenne Twister (std::mt19937).

Constructor & Destructor Documentation

PRG()

evoplex::PRG::PRG ( unsigned int  seed )

explicit

PRG constructor.

Parameters

seed	The pseudo-random generator seed.

Member Function Documentation

bernoulli()

bool evoplex::PRG::bernoulli ( double  p )

inline

Bernoulli distribution.

It generates a random boolean according to the discrete probability function, where the probability of true is p and the probability of false is (1-p).
