Detailed Description

A portable linear congruential generator based on the rng developed by Park and Miller.

This rng is implemented in PMrand function.

Constructor & Destructor Documentation

PM_LCG::PM_LCG (  int    seed = 0 )  [inline]

Constructor. If no argument is provided, the seed is set to zero, so the rng * is initialized with the current time information.

---

Member Data Documentation

int PM_LCG::jseed [private]

Use to initialize the generator. If zero, time is used to generate the random seed.
