Genetic Algorithms

Genotype

Generic Structure

## Creating and Running Populations ```js for (var k = 0; k < 1000; k++) genotypes.push(Path.createGenotype(/* ... */)); var mutators = []; for (var k = 0; k < 4; k++) mutators.push(Path.createMutator()); engine = new simplega.Engine({ minimize: true }); engine.setPopulation(genotypes); engine.setMutators(mutators); // var newgenotypes = engine.nextPopulation(); best = simplega.getBestGenotype(newgenotypes, { minimize: true }); ```

Many Layers

## Creating and Training a Network ```js var network = sn.network([6, 10, 3]); var outputs = network.outputs([0, 0, 1, 1, 0, 0]); console.dir(outputs); for (var k = 0; k < 20; k++) { network.train([0, 0, 1, 1, 0, 0], [0, 1, 0], 0.1); // .... } ```
