Implementation of Marsaglia Random Engine. This is an implementation of Marsaglia Random engine, which for most use cases is a better fit than other solutions. Very simple mathematical formula to generate pseudorandom integer, so its crazy fast.

This implementation of the Marsaglia Engine is seeded by random.h default random engine. RandomEngine is only seeded once so its not a performance issue.

Example Use: Using Marsaglia Engine with RandomWalk

Markov::Model<char> model;
Model.import("model.mdl");
char* res = new char[11];
Markov::Random::Marsaglia MarsagliaRandomEngine;
for (int i = 0; i < 10; i++) {
    this->RandomWalk(&MarsagliaRandomEngine, 5, 10, res); 
    std::cout << res << "\n";
 }

Example Use: Generating a random number with Marsaglia Engine

Markov::Random::Marsaglia me;
std::cout << me.random();
