Parameter Optimization Loop End: No Flow variable with objective function value shows up.

Hi guys!

I’m new to KNIME and I’m trying to execute the parameter Optimisation Loop, unfortunately I don’t get a flow variable displayed in the parameter Optimisation Loop End Node (see picture).

I would rather appreciate your help!

Hi @janletsgo and welcome to the forum.

Try using the “regular” / non-Javascript version of the Scorer node for this purpose.
