Detailed Description

This class is the default random implementation with the 'Mersenne Twister' algorithm.

Random Number generator 'Mersenne Twister' * * This random number generator is described in the article by * M. Matsumoto & T. Nishimura, in: * ACM Transactions on Modeling and Computer Simulation, * vol. 8, no. 1, 1998, pp. 3-30. * Details on the initialization scheme can be found at * http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html * * Experts consider this an excellent random number generator. *

Member Function Documentation

unsigned int genetiK::util::RandomDefault::getNextInt (  unsigned int  max  )  [virtual]

Returns the next pseudorandom integer. This method returns the next pseudorandom integer. Returns an unsigned int greater than or equal to 0 and less than max; Parameters: max  The return value upperbound Implements genetiK::util::Random.

unsigned int genetiK::util::RandomDefault::getNextInt (   )  [virtual]

Returns the next pseudorandom integer. This method returns the next pseudorandom integer. Returns an unsigned int greater than or equal to 0 and less than 4294967296; Implements genetiK::util::Random.

double genetiK::util::RandomDefault::getNextReal (   )  [virtual]

Returns the next pseudorandom real. This method returns the next pseudorandom double. Returns a double greater than or equal to 0.0 and less than 1.0; Implements genetiK::util::Random.
