[Couenne] Preprocessing options

[Akshay Gupte]

Hi all,
Are there specific options to control preprocessing in Couenne ? Couenne seems to be branching on very few nodes in a reasonably long time for some of my large-scale models. I am looking at ways to control the number of variables whose bounds are tightened at each node and other preprocessing steps. I could not find anything specific in the Couenne or Bonmin manual that addresses this. 

Does anyone know where (and if its easy) to tweak the source code ?

Akshay.
