Re: [cilib-devel] Problem with value setting

[Marde G. <mg...@cs...>]

Hi everyone,

An example xml file is attached.

The part to focus on is the following:

<iterationStrategy class="moo.iterationstrategies.ArchivingIterationStrategy">
		<archive class="moo.archive.constrained.SetBasedConstrainedArchive" capacity="200">
                    <pruningSelection class="util.selection.recipes.ElitistSelection"/>
                </archive>

You can set the comparator as follows:
<iterationStrategy class="moo.iterationstrategies.ArchivingIterationStrategy">
		<archive class="moo.archive.constrained.SetBasedConstrainedArchive" capacity="200">
                    <pruningSelection class="util.selection.recipes.ElitistSelection">
                         <comparator class="util.selection.ordering.DefaultComparator/>
                    </pruningSelection>
                </archive>

However, if I change the DefaultComparator to any other new comparator (for example when I want to sort solutions based on their distance from other solutions in the archive and not based on fitness) it doesn't make the change. It keeps the DefaultComparator. I guess this is the same as with the archive size issue.

This is based on the usage.

Awaiting XML file to inspect how this is being used. The issue is more than 
likely related to the use of the entity.operator.selection classes - which 
need to be updated to use the relavant recipe classes.
