Methods for the edaTerminate generic function.

edaTerminateMaxGen(eda, gen, fEvals, pop, popEval)
edaTerminateMaxEvals(eda, gen, fEvals, pop, popEval)
edaTerminateEval(eda, gen, fEvals, pop, popEval)
edaTerminateEvalStdDev(eda, gen, fEvals, pop, popEval)
edaTerminateCombined(...)

`eda`	`EDA` instance.
`gen`	Generation.
`fEvals`	Evaluations of the objective function.
`pop`	Matrix with one row for each solution in the population.
`popEval`	Vector with the evaluation of each solution in `pop`.
`...`	Functions that implement termination methods.

Termination methods decide when to stop the main loop of the EDA. The following termination methods are implemented.

edaTerminateMaxGen: Stop when a maximum number of generations has been reached. The parameter maxGen specifies the number of generations (default value: 100). This is the default method of the edaTerminate generic function.
edaTerminateMaxEvals: Stop when a maximum number of evaluations of the objective function has been reached. The parameter maxEvals specifies the number of evaluations (default value: 1000.)
edaTerminateEval: Stop when a given value of the objective function has been reached. The parameters fEval (default value: 0) and fEvalTol (default value: 1e-06) set the value of the objective function and the tolerance, respectively.
edaTerminateEvalStdDev: Stop when the standard deviation of the evaluation of the solutions in the population is less than the value given by the parameter fEvalStdDev (default value: 1e-02)

edaTerminateCombined: Evaluate all the termination criteria specified in ... and stop if (at least) one of them returns TRUE.

A logical value that indicates if the algorithm should stop.
