GA == Genetic Algorithm Pareto (wave) front == In game theory a Pareto move is one that gives one or more players a higher payoff without reducing the payoff to the others. A Pareto optimum is where all the players are at a point where none can increase their benefit without reducing that of another. This may (is probably) not a stable Nash equilibrium point...the Prisoner's Dilemma is a good example.
In TOS a list of apparently random (phone) numbers is par for the course...so probably a Nash. I am not much of an optimizer myself.
