/**

 * Main orchestrator class for evolutionary algorithms, managing the complete evolution process.

 * <p>EASystem serves as the central coordinator that brings together all components of an evolutionary algorithm

 * including genetic operators, selection strategies, evaluation functions, and termination criteria. It manages the

 * evolutionary cycle and provides a unified interface for running optimizations.

 * <p>The system coordinates the following evolutionary process:

 * <ol>

 * <li><strong>Initialization</strong>: Generate initial population of random genotypes</li>

 * <li><strong>Evaluation</strong>: Compute fitness values for all individuals</li>

 * <li><strong>Selection</strong>: Choose parents for reproduction based on fitness</li>

 * <li><strong>Reproduction</strong>: Create offspring through crossover and mutation</li>

 * <li><strong>Replacement</strong>: Integrate offspring into next generation</li>

 * <li><strong>Termination check</strong>: Determine if stopping criteria are met</li>

 * <li><strong>Iteration</strong>: Repeat until termination conditions are satisfied</li>

 * </ol>

 * <p>Key responsibilities include:

 * <ul>

 * <li><strong>Population management</strong>: Maintaining population size and diversity</li>

 * <li><strong>Genetic operator coordination</strong>: Applying crossover, mutation, and selection</li>

 * <li><strong>Fitness evaluation orchestration</strong>: Managing parallel and synchronous evaluation</li>

 * <li><strong>Evolution monitoring</strong>: Providing hooks for logging and progress tracking</li>

 * <li><strong>Resource management</strong>: Efficient memory usage and computation distribution</li>

 * </ul>

 * <p>Configuration components:

 * <ul>

 * <li><strong>EAConfiguration</strong>: Defines genetic representation and operator policies</li>

 * <li><strong>EAExecutionContext</strong>: Provides runtime services and factory implementations</li>

 * <li><strong>FitnessEvaluator</strong>: Computes quality measures for candidate solutions</li>

 * <li><strong>Termination criteria</strong>: Determines when to stop evolution</li>

 * </ul>

 * <p>The system supports various evolutionary paradigms:

 * <ul>

 * <li><strong>Genetic Algorithms</strong>: Traditional binary and real-valued optimization</li>

 * <li><strong>Genetic Programming</strong>: Evolution of tree-structured programs</li>

 * <li><strong>Evolution Strategies</strong>: Real-valued optimization with adaptive parameters</li>

 * <li><strong>Multi-objective optimization</strong>: Pareto-based optimization with multiple objectives</li>

 * </ul>

 * <p>Example usage:

 * <pre>{@code

 * // Configure the evolutionary algorithm

 * EAConfiguration<Double> config = EAConfigurationBuilder.<Double>builder()

 *     .chromosomeSpecs(DoubleChromosomeSpec.of(10, -5.0, 5.0))

 *     .parentSelectionPolicy(Tournament.of(3))

 *     .mutationPolicy(RandomMutation.of(0.1))

 *     .build();

 * // Set up execution context

 * EAExecutionContext<Double> context = EAExecutionContexts.forScalarFitness();

 * // Create fitness evaluator

 * Fitness<Double> fitness = genotype -> {

 *     // Implement problem-specific fitness function

 *     return computeFitness(genotype);

 * };

 * // Build and run the evolutionary system

 * EASystem<Double> system = EASystemFactory.from(config, context, fitness);

 * EvolutionResult<Double> result = system.evolve(

 *     populationSize: 100,

 *     termination: Terminations.generations(1000)

 * );

100

 * }</pre>

101

102

 * <p>Thread safety: EASystem instances are generally not thread-safe and should not be shared between multiple threads

103

 * without external synchronization. However, the system supports parallel fitness evaluation internally when configured

104

 * appropriately.

105
