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. </div><div><br></div><div>Does anyone know where (and if its easy) to tweak the source code ?<br><div>
