Detailed Description

template<class Engine = boost::mt19937>
class FT::ExponentialCheater< Engine >

ExponentialCheater : a cheater that cheat using an exponential distribution based either on the age of the current generation or the position in the sequential order depending on the cheat_mode.
Reminder: cheat are distributed with probability density function p(x) = lambda * exp(-lambda * x), where lambda is the parameter of the constructor.
