Class GPInitializer

  • All Implemented Interfaces:
    Setup, Singleton, java.io.Serializable

    public class GPInitializer
extends SimpleInitializer
    GPInitializer is a SimpleInitializer which sets up all the Cliques, ( the initial [tree/node]constraints, types, and function sets) for the GP system.

    Note that the Cliques must be set up in a very particular order:

    1. GPType
    2. GPNodeConstraints
    3. GPFunctionSets
    4. GPTreeConstraints

    Parameter bases

    gp.type GPTypes
    gp.nc GPNodeConstraints
    gp.tc GPTreeConstraints
    gp.fs GPFunctionSets

      • setup

        public void setup(EvolutionState state,
                  Parameter base)
        Description copied from interface: Setup
        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.
        Specified by:
        setup in interface Setup
        Overrides:
        setup in class SimpleInitializer

      • setupTypes

        public void setupTypes(EvolutionState state,
                       Parameter base)
        Sets up all the types, loading them from the parameter file. This must be called before anything is called which refers to a type by name.

      • postProcessTypes

        public void postProcessTypes()
        Assigns unique integers to each atomic type, and sets up compatibility arrays for set types. If you add new types (heaven forbid), you should call this method again to get all the types set up properly. However, you will have to set up the function sets again as well, as their arrays are based on these type numbers.

      • setupNodeConstraints

        public void setupNodeConstraints(EvolutionState state,
                                 Parameter base)
        Sets up all the GPNodeConstraints, loading them from the parameter file. This must be called before anything is called which refers to a type by name.

      • setupTreeConstraints

        public void setupTreeConstraints(EvolutionState state,
                                 Parameter base)
        Sets up all the GPTreeConstraints, loading them from the parameter file. This must be called before anything is called which refers to a type by name.
