Termination Criteria

Termination criteria are used to define how the algorithm stops.

Configuring

A number of alternatives are available in JECoLi:

  • Maximum number of iterations (class IterationTerminationCriteria)
  • Maximum number of function evaluations (class NumberOfFunctionEvaluationsTerminationCriteria);
  • Maximum computation time (class RunTimeTerminationCriteria);
  • Reaching a given fitness target (class FitnessTargetTerminationCriteria).


Example:

ITerminationCriteria terminationCriteria = new IterationTerminationCriteria(numberGenerations);

Defining new ones

Define a class that implements interface ITerminationCriteria.

The criteria can be defined over the statistics calculated: time, number of iterations, number of function evaluations, maximum/minimum/mean fitness, standard deviation, etc.

Examples are available in the package core.terminationcriteria.
