Concatenate rows in Parameter Optimization Loop

Hi guys,


I'm trying to concatenate all results inside a Parameter Optimization Loop (see attachment).

But I get cannot concatenate results from each run into a single table?

Is there a simple solution? (possibly using the concatenate node?)





Ok, found a solution with a CSV writer in append mode. 

Possibly not the fastest solution, but it works.

For all wo are interested in, the workflow is appended.




ps/ use "Delete Files" node to initialize the CSV file otherwise it will grow with every new run.
