Generalize set of points using VoronoiDiagrammer and a loop

Hi everyone,

I have a set of N points that I would like to generalize as follows :

1. Generate Voronoi diagram for the set ;
2. Eliminate the point with the smallest Voronoi cell area ;
3. Redo the same process (generate Voronoi diagram for the remaining points then eliminate the smallest one) until 30% of the points are eliminated

I have tried to implement the process in FME but got stuck on how to do it using a custom loop transformer and how to implement the 30% threshold that depends on the number of features entering the transformer.

Any help is much appreciated.

Many thanks.
