 Reversi 
https://play.google.com/store/apps/details?id=com.neuralplay.android.reversi
The NeuralPlay Reversi AI sports a strong Artificial Neural Network.  More conventional brute force methods applying game tree search to Reversi work well, however a well-trained neural network can offer better performance given cpu time and processing constraints.    The limited processing power of a cell phone illustrates the advantages of a well-trained neural network over a brute-force approach. 

Currently, NeuralPlay Reversi Free on android offers many fun and useful features, including
  • six computer levels varying from very easy to very difficult
  • human vs computer play
  • human vs human play
  • computer vs computer play
  • undo move
  • optional display of legal moves
  • optional display of last move played
  • play on 4x4 and 6x6 board sizes for learning
Can you beat the Neural Network?
Try Reversi on your phone or tablet!  Available on Google Play or the Amazon Appstore.

Genetic Algorithm Explorer
Learn about Genetic Agorithms (GAs) with Genetic Algorithm Explorer.
  • Let the built-in tutorial guide you as you explore the world of GAs.
  • Watch an animation of the evolutionary process including crossover and mutation as the GA solves the Bulls and Cows code-breaking problem.
  • Watch and view the solution paths as the GA solves the Travelling Salesman Problem.
  • Graphically view the results of the evolutionary process over the course of generations.
  • Tweak the GA parameters: population size, crossover rate, mutation rate, and elitism to explore the effects.
  • Tweak the problem parameters for the Travelling Salesman Problem and the Bulls and Cows Problem.
