Hello,
in my model I would like to iterate through the maximum number of generations. Does rapidminer re-use the results from the previous step in order to save calculation time? I mean after finishing the calculation with only one feature (and saving this result to file, or something similar) it can directly continue to add the next attributes to the best n-features and continue instead of starting again from 1 for the next iteration ...
<operator name="Root" class="Process" expanded="yes">
<parameter key="logfile" value="logfile.log"/>
<parameter key="resultfile" value="result.res"/>
<operator name="ExcelExampleSource" class="ExcelExampleSource">

<parameter key="first_row_as_names" value="true"/>
<parameter key="create_label" value="true"/>
</operator>
