DEMO for testing the termination options
This function provides an example for using some of the termination
options in an optimization.
The options are defined by the structure method providing a
higher flexibility.
Change the variable TermVariant to one of the possible numbers and run the
function. Different termination methods will be used. Over the run of the
optimization the value of the termination parameter can be checked on
the screen. After some runs you will get a feeling for the validity or
utility of the different options.
Be carefull, use all the time one of the garanteed termination option
as well (max generations and max time). Most of the other methods will
very often never terminate (depends on the problem and the used operator
settings). And when the other options terminate, they very often terminate
too early.
However, play around with the methods and their settings, change the
objective function (standard is 'objfun1') or change other parameters. At
the end you will know, which of the termination methods is suited best
for your problem at hand.
