HarelKorenFastMultiscale Layout - Strength of the repulsive force between vertices

Hi,

I'm unable to find the property of a HarelKorenFastMultiscale layout where I can set the strength of the repulsive force between vertices.

Anyone can help?

Carlos:

There is no such property.

The researcher who implemented NodeXL's Harel-Koren layout algorithm is no longer with our group, but when I look through the paper on which he based his implementation ("A Fast Multi-Scale Method for Drawing Large Graphs," David Harel and Yehuda Koren, 2000), it's not clear to me which part of the algorithm could be parameterized in a useful manner.  If you are familiar with the Harel-Koren algorithm and you'd like to analyze the source code (it's in \Layouts\Layouts\HarelKoren\HarelKorenFastMultiscaleLayoutInternal.cs), I'd be interested in hearing if it has anything analogous to Fruchterman-Reingold's "C" constant.
