RANDOM OFFSET CURVES

I need do random offset curves with maximum and minimum distance at the same time with Grassoper plugin but I dont get good results.

The file RANDOM OFFSET.ghx is the frist step to do this work.

In the file RANDOM OFFSET.3dm is one exemple from 3 curves and 2 curves are inside of the last curve.

I try to put work this file  RANDOM OFFSET.ghx but the result are very negative.

I do one small explanation of every step in the file RANDOM OFFSET.pdf.

Is possibel upadted this Grassoper file to do Random Offset with good quality?

Thank you Line
