Example Code

Example 1: Using ScientificGrammar

try

{

AmibaFactory<Double> factory = new ScientificFactory();

EvolutionEngine<Double> engine = new EvolutionEngine<Double>(

new File("AmibaConfig.xml"), factory);

// evolve

Population<Double> evolvedPopulation = engine.evolve();

//the result can also be obtained at an intermediate stage

EvolutionResult<Double> result = evolvedPopulation.getEvolutionResult();

List<FitnessCase<Double>> testCases = new DoubleFitnessCaseLoader()

.load("test/data/TestSet.xml");

System.out.println("Test fitness : "

+ result.getBestIndividual().evaluateFitness(testCases));

List<Double> calculated = result.getBestIndividual().useOn(testCases);

for (int i = 0; i < calculated.size(); i++)

{

System.out.println("Expected : " + testCases.get(i).getValue() + " Calculated : "

+ calculated.get(i));

}

result.save(new FileOutputStream(new File("result")));

}

catch (AmibaException e)

{

e.printStackTrace();

}

catch (FileNotFoundException e)

{

e.printStackTrace();

}
