This example implements a genetic algorithm framework that demonstrates evolutionary computation. The Genetic class provides the core GA infrastructure — chromosome representation, fitness evaluation, crossover, and mutation — while TestGenetic runs an optimization experiment that evolves a population toward a target solution.

• Java 8+
• Maven 3.6+

# Run the genetic algorithm test
make test

# Or manually
mvn install
mvn exec:java -Dexec.mainClass="com.markwatson.geneticalgorithm.TestGenetic"

• Genetic.java — Core GA engine with selection, crossover, and mutation operators
• TestGenetic.java — Test harness that runs the GA and prints generational fitness results
