Returns the number of nodes, constrained by g.test(...) in the subtree for which this GPNode is root. This might be sped up by cachin

Returns the default base for this prototype. This should generally be implemented by building off of the static base() method on the

Returns the adjusted fitness metric, which recasts the fitness to the half-open interval (0,1], where 1 is ideal and 0 is worst. Same

Produce random sample points between min and max, inclusive, in each dimension.

Throws an IndexOutOfBoundsException if index is inappropriate. Not called get() because this would conflict with get() methods in IntBag etc.

Splits the rule set into n pieces, according to points, which must be sorted. The rules in each piece are cloned and added to the equivalent se

Calls super implementation and after that closes the collective.

Evaluates the individual in ind, if necessary (perhaps not evaluating them if their evaluated flags are true), and sets their fitness

The contributor must have a name which uniquely identifies it in the collective.

Handle a start/resume event.

This returns the fully qualified and unique name of the agent that is used everywhere, composed by type.job.id

Called when the agent has a new message. The agent can reply to the message by simply using the method <code>m.setReply(Object)</code> in this method.
