Constructor Detail

Sim_geometric_obj

public Sim_geometric_obj(String name,
                         double prob)
Constructor with which Sim_system is allowed to set the random number generator's seed

Parameters:
name - The name to be associated with this instance
prob - The probability of success

Sim_geometric_obj

public Sim_geometric_obj(String name,
                         double prob,
                         long seed)
The constructor with which a specific seed is set for the random number generator

Parameters:
name - The name to be associated with this instance
prob - The probability of success
seed - The initial seed for the generator, two instances with the same seed will generate the same sequence of numbers
