Subject: [PATCH] Update to allow using previous bounds with categories.

With this update we can use bounds from previous runs with categories.
This allows, for example, to reduce the iteration space when using categories. For this it's necessary to have somehow saved the bounds resulting form previous runs of the optimizer.
