Class GrammarBitStringRepresentation

java.lang.Object

com.knezevic.edaf.v3.repr.impl.GrammarBitStringRepresentation

All Implemented Interfaces:

Representation<BitString>

public final class GrammarBitStringRepresentation
extends Object
implements Representation<BitString>

Fixed-length bitstring representation for grammar-encoded GP trees.

Bitstrings are decoded through BFS production choices, enabling direct compatibility with existing binary/discrete EDA drivers.
