Class Documentation

template<typename ProblemType>
class ioh::logger::observer

A class of methods of setting triggers recording evaluations.

Four methods is introduced here:

1. Recording evaluations by a static interval.

2. Recording complete evaluations.

3. Recording evaluations as the best found solution is updated.

4. Recording evaluations at pre-defined points or/and with a static number for each exponential bucket.
