Need for Classes

Modules are connected. The information passed between these Modules may be a class of type

  • Solutions in the case of an optimization or
  • Data in the case of learning

Often, Modules look similar, and someone writing a new Module doesn't want to implement all interface methods by hand.

For these cases, we wrote the abstract classes

  • Optimizers in the case of an optimization algorithm
  • Problems in the case of an optimization problem
  • Learners in the case of a learning algorithm

These classes already implement most of the necessary methods. A writer of an optimizer just has to implement the algorithm itself and no other details such as checking or connecting.

Similarly, a writer of a problem just has to implement the evaluate(...) method of the Problem class.

In a learner, the method to override is run() . It executes the learning algorithm.
