The optimization extension contains some nodes for performing all kinds of optimization tasks, such as parameter optimization or multiobjective subset selection. The nodes can be found in the node repository under KNIME Labs/Optimization. The example workflow server contains some annotated workflows using the available nodes in the folder 014_Optimization.
In addition to the nodes, the plug-in contains generic implementations of a single-objective and a multi-object genetic algorithm (NSGA-2) that can be used in other plug-ins.
To get access to the optimization nodes, download first the current version of KNIME. Afterwards use the update mechanism ("File -> Install KNIME extension...") to include the KNIME Optimization extension. It can be found in the KNIME Labs category.
