Class ExplicitNeatNodeLayout

java.lang.Object

net.bmahe.genetics4j.neat.spec.ExplicitNeatNodeLayout

All Implemented Interfaces:

NeatNodeLayout

public class ExplicitNeatNodeLayout
extends Object
implements NeatNodeLayout

Node layout with explicitly declared, ordered input and output IDs.

The constructor defensively copies both lists. IDs must be unique, non-negative, disjoint between inputs and outputs, and outside the configured hidden-node range.

Constructor Details

ExplicitNeatNodeLayout

public ExplicitNeatNodeLayout(List<Integer> _inputNodeIds,
 List<Integer> _outputNodeIds,
 long _hiddenNodeIdStartInclusive,
 long _hiddenNodeIdEndExclusive)

Creates an explicit node layout.

Parameters:

_inputNodeIds - input IDs in vector order

_outputNodeIds - output IDs in vector order

_hiddenNodeIdStartInclusive - inclusive hidden-node range start

_hiddenNodeIdEndExclusive - exclusive hidden-node range end

Throws:

NullPointerException - if either external-ID list or one of its elements is null

IllegalArgumentException - if the external IDs or hidden-node range are invalid
