The parameter <var>parameters</var> is a list of key value pairs where the keys are of the form <code>OperatorName.parameter_name</code> and the value is a comma separated list of values (as for the GridParameterOptimization operator). <br/> The operator returns an optimal <A HREF="../../../../com/rapidminer/operator/meta/ParameterSet.html" title="class in com.rapidminer.operator.meta"><CODE>ParameterSet</CODE></A> which can as well be written to a file with a <A HREF="../../../../com/rapidminer/operator/io/ParameterSetLoader.html" title="class in com.rapidminer.operator.io"><CODE>ParameterSetLoader</CODE></A>. This parameter set can be read in another process using an <A HREF="../../../../com/rapidminer/operator/io/ParameterSetLoader.html" title="class in com.rapidminer.operator.io"><CODE>ParameterSetLoader</CODE></A>. <br/> The file format of the parameter set file is straightforward and can also easily be generated by external applications.
