 * Represents a neural network chromosome in the NEAT (NeuroEvolution of Augmenting Topologies) algorithm.
18 
 *
19 
 * <p>NeatChromosome is the core genetic representation in NEAT, encoding a neural network as a collection of
20 
 * connections between nodes. Each chromosome defines a complete neural network topology with input nodes, output nodes,
21 
 * optional hidden nodes, and weighted connections. The chromosome maintains essential parameters for network
22 
 * construction and genetic operations.
23 
 *
24 
 * <p>Key characteristics:
25 
 * <ul>
26 
 * <li><strong>Network topology</strong>: Encoded as a list of connections with innovation numbers</li>
27 
 * <li><strong>Node organization</strong>: Fixed input/output nodes with dynamically added hidden nodes</li>
28 
 * <li><strong>Weight constraints</strong>: Configurable minimum and maximum weight bounds</li>
29 
 * <li><strong>Innovation tracking</strong>: Connections sorted by innovation number for genetic alignment</li>
30 
 * </ul>
31 
 *
32 
 * <p>NEAT algorithm integration:
33 
 * <ul>
34 
 * <li><strong>Structural mutations</strong>: Add/delete nodes and connections while preserving innovation tracking</li>
35 
 * <li><strong>Weight mutations</strong>: Modify connection weights within specified bounds</li>
36 
 * <li><strong>Genetic crossover</strong>: Innovation-number-based gene alignment for topology recombination</li>
37 
 * <li><strong>Compatibility distance</strong>: Genetic similarity measurement for speciation</li>
38 
 * </ul>
39 
 *
40 
 * <p>Network structure:
41 
 * <ul>
42 
 * <li><strong>Input and output nodes</strong>: Stable ordered IDs declared by the node layout</li>
43 
 * <li><strong>Hidden nodes</strong>: IDs allocated from the layout's hidden-node namespace</li>
44 
 * <li><strong>Connections</strong>: Weighted links between nodes with enable/disable states and innovation numbers</li>
45 
 * </ul>
46 
 *
47 
 * <p>Common usage patterns:
48 
 *
49 
 * <pre>{@code
50 
 * // Create a basic NEAT chromosome
51 
 * List<Connection> connections = List.of(
52 
 * 		Connection.of(0, 2, 0.5f, true, 0), // input 0 -> output 0
53 
 * 			Connection.of(1, 3, -0.3f, true, 1) // input 1 -> output 1
54 
 * );
55 
 *
56 
 * NeatChromosome chromosome = new NeatChromosome(2, // number of inputs
57 
 * 		2, // number of outputs
58 
 * 		-1.0f, // minimum weight
59 
 * 		1.0f, // maximum weight
60 
 * 		connections);
61 
 *
62 
 * // Access chromosome properties
63 
 * int numAlleles = chromosome.getNumAlleles();
64 
 * List<Integer> inputNodes = chromosome.getInputNodeIds();
65 
 * List<Integer> outputNodes = chromosome.getOutputNodeIds();
66 
 * List<Connection> allConnections = chromosome.getConnections();
67 
 *
68 
 * // Create feed-forward network for evaluation
69 
 * FeedForwardNetwork network = new FeedForwardNetwork(Set.copyOf(chromosome.getInputNodeIds()),
70 
 * 		Set.copyOf(chromosome.getOutputNodeIds()),
71 
 * 		chromosome.getConnections(),
72 
 * 		Activations::sigmoid);
73 
 * }</pre>
74 
 *
75 
 * <p>Genetic operations compatibility:
76 
 * <ul>
77 
 * <li><strong>Mutation operations</strong>: Compatible with weight, add-node, add-connection, and state mutations</li>
78 
 * <li><strong>Crossover operations</strong>: Innovation numbers enable proper gene alignment between parents</li>
79 
 * <li><strong>Selection operations</strong>: Supports species-based selection through compatibility distance</li>
80 
 * <li><strong>Evaluation operations</strong>: Can be converted to executable neural networks</li>
81 
 * </ul>
82 
 *
83 
 * <p>Innovation number organization:
84 
 * <ul>
85 
 * <li><strong>Sorted connections</strong>: Connections automatically sorted by innovation number</li>
86 
 * <li><strong>Genetic alignment</strong>: Enables efficient crossover and compatibility calculations</li>
87 
 * <li><strong>Historical tracking</strong>: Maintains evolutionary history of structural changes</li>
88 
 * <li><strong>Population consistency</strong>: Same innovation numbers across population for same connection types</li>
89 
 * </ul>
90 
 *
91 
 * <p>Performance considerations:
92 
 * <ul>
93 
 * <li><strong>Immutable connections</strong>: Connection list is sorted once and made immutable</li>
94 
 * <li><strong>Efficient lookup</strong>: Node indices computed deterministically for fast access</li>
95 
 * <li><strong>Memory efficiency</strong>: Only stores necessary network topology information</li>
96 
 * <li><strong>Cache-friendly</strong>: Sorted connections improve cache locality for genetic operations</li>
97 
 * </ul>
98 
 *
99 
 * <p>Integration with NEAT ecosystem:
100 
 * <ul>
101 
 * <li><strong>Chromosome factories</strong>: Created by NeatConnectedChromosomeFactory and similar</li>
102 
 * <li><strong>Genetic operators</strong>: Processed by NEAT-specific mutation and crossover handlers</li>
103 
 * <li><strong>Network evaluation</strong>: Converted to FeedForwardNetwork for fitness computation</li>
104 
 * <li><strong>Speciation</strong>: Used in compatibility distance calculations for species formation</li>
