Class ContiguousNeatNodeLayout

java.lang.Object
net.bmahe.genetics4j.neat.spec.ContiguousNeatNodeLayout
All Implemented Interfaces:
NeatNodeLayout
public class ContiguousNeatNodeLayout extends Object implements NeatNodeLayout
Node layout using the traditional contiguous NEAT external IDs.

Inputs occupy [0, numInputs) and outputs occupy [numInputs, numInputs + numOutputs). The configured hidden-node range must not overlap those external IDs.

  • Field Details

    • numInputs

      private final int numInputs

    • numOutputs

      private final int numOutputs

    • hiddenNodeIdStartInclusive

      private final long hiddenNodeIdStartInclusive

    • hiddenNodeIdEndExclusive

  • Constructor Details

    • ContiguousNeatNodeLayout

      public ContiguousNeatNodeLayout(int _numInputs, int _numOutputs, long _hiddenNodeIdStartInclusive, long _hiddenNodeIdEndExclusive)
      Creates a contiguous node layout.
      Parameters:
      _numInputs - number of input nodes; must be positive
      _numOutputs - number of output nodes; must be positive
      _hiddenNodeIdStartInclusive - inclusive hidden-node range start
      _hiddenNodeIdEndExclusive - exclusive hidden-node range end
      Throws:
      IllegalArgumentException - if the counts or hidden-node range are invalid, or if the ranges overlap
