What is CONSUMED?

[mariosky]

This is a counter of the number of messages the controller has taken from the queue. This count is analogous to the number of generations, CONSUMED*iterations and roughly equal to the number of evaluations. Some algorithms don't need to evaluate all the members of a population on each generation. Because of this, this counter is used to terminate the current execution. This is used together with MAX_MESSAGES.
