/**
9 
 * A chromosome implementation that represents genetic information as an array of integer values.
10 
 *
11 
 * <p>IntChromosome is widely used for discrete optimization problems where solutions can be encoded as sequences of
12 
 * integer values within specified ranges. Each position in the array represents a gene, and the integer value at that
13 
 * position represents the allele.
14 
 *
15 
 * <p>This chromosome type is particularly suitable for:
16 
 * <ul>
17 
 * <li><strong>Combinatorial optimization</strong>: Problems with discrete decision variables</li>
18 
 * <li><strong>Parameter optimization</strong>: Integer hyperparameters, configuration settings</li>
19 
 * <li><strong>Permutation encoding</strong>: When combined with appropriate operators</li>
20 
 * <li><strong>Resource allocation</strong>: Assignment and scheduling problems</li>
21 
 * <li><strong>Graph problems</strong>: Node labeling, path encoding</li>
22 
 * </ul>
23 
 *
24 
 * <p>Key features:
25 
 * <ul>
26 
 * <li><strong>Bounded values</strong>: All integers are constrained to [minValue, maxValue]</li>
27 
 * <li><strong>Fixed length</strong>: Chromosome size is determined at creation time</li>
28 
 * <li><strong>Immutable</strong>: Values cannot be changed after construction</li>
29 
 * <li><strong>Type-safe</strong>: Compile-time guarantees for integer operations</li>
30 
 * </ul>
31 
 *
32 
 * <p>The chromosome maintains bounds information which is used by genetic operators to ensure that crossover and
33 
 * mutation operations produce valid offspring within the specified constraints.
