Method Summary
 java.lang.Object clone()
          Creates a new individual cloned from a prototype, and suitable to begin use in its own evolutionary context.
 void describe(Individual ind, EvolutionState state, int threadnum, int log, int verbosity)
           
 void evaluate(EvolutionState state, Individual ind, int subpopulation, int threadnum)
          Evaluates the individual in ind, if necessary (perhaps not evaluating them if their evaluated flags are true), and sets their fitness appropriately.
 void setup(EvolutionState state, Parameter base)
          Sets up the object by reading it from the parameters stored in state, built off of the parameter base base.

Method Detail

clone

public java.lang.Object clone()
Description copied from interface: Prototype
Creates a new individual cloned from a prototype, and suitable to begin use in its own evolutionary context.

Typically this should be a full "deep" clone. However, you may share certain elements with other objects rather than clone hem, depending on the situation:

Implementations.

Specified by:
clone in interface Prototype
Overrides:
clone in class GPProblem

setup

public void setup(EvolutionState state,
                  Parameter base)
Description copied from interface: Prototype
Sets up the object by reading it from the parameters stored in state, built off of the parameter base base. If an ancestor implements this method, be sure to call super.setup(state,base); before you do anything else.

For prototypes, setup(...) is typically called once for the prototype instance; cloned instances do not receive the setup(...) call. setup(...) may be called more than once; the only guarantee is that it will get called at least once on an instance or some "parent" object from which it was ultimately cloned.

Specified by:
setup in interface Prototype
Specified by:
setup in interface Setup
Overrides:
setup in class GPProblem

evaluate

public void evaluate(EvolutionState state,
                     Individual ind,
                     int subpopulation,
                     int threadnum)
Description copied from interface: SimpleProblemForm
Evaluates the individual in ind, if necessary (perhaps not evaluating them if their evaluated flags are true), and sets their fitness appropriately.

Specified by:
evaluate in interface SimpleProblemForm
Overrides:
evaluate in class Problem

describe

public void describe(Individual ind,
                     EvolutionState state,
                     int threadnum,
                     int log,
                     int verbosity)
Specified by:
describe in interface SimpleProblemForm
Overrides:
