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

Hi, I have a Multi-objective Genetic Algorithm that i am optimising, the algorithm outputs the values below. The first objective is maximising the efficiency of the network by lowering energy depletion(minimising energy depletion) and the second is maximising the number of nodes to achieve full

uh... what are those values of? secondarily, why do some of them seem to show as telephone numbers? MS T O wrote: Hi, I have a Multi-objective Genetic Algorithm that i am optimising, the algorithm outputs the values below. The first objective is maximising the efficiency of the network

So are those values lying on the pareto front found by the GA? I think we need more info to figure out what you are trying to accomplish! For a start, what were the design variables of your optimisation? Chris Brooks Sent from my ASUS Eee Pad Michael Schippling sc...@santafe.edu wrote:

OK, this is for my own amusement only... What the heck are you guys talking about? By pareto front do you mean the, slowly, improving set of values discovered by the GA? I've only heard pareto optimum in game theory, not GA's, but it seems to fit. If that list of numbers is meant to represent

Sure, it`s widely used in multiobjective optimisation be it GAs or other evolutionary algorithms. I read the table of numbers as being two columns for the 2 objectives, and 11 rows for best GA results so far? Just trying to understand the optimisation problem, as my background is in
