Updating variables takes time

Open DillonJ opened this issue 1 year ago • 5 comments

I have a model with 500 nodes and 700 branches. It's performs pretty well considering but it takes 30 seconds per window at "updating variables". Feels like we should be able to do better?

Any thoughts @manuelma

contingency_is_binding?

No, with LODF constraint active

Yeah, sorry, contingency is binding has nothing to do with updating variables.

Updating variables at the moment is fixing the history after rolling (to the results of the last solve) and also fixing values and restoring lower and upper bounds.

I think I can make it faster, I have some work on a branch but need to test it before merging into master.

That branch is already merged. I was testing it with a model where it took 4 seconds per window to 'update variables' - but it was 5 seconds before merging, so either @DillonJ 's model was taking 30 seconds because of other issues of because it's just larger...

@DillonJ Is this still an active Issue? If so, can we maybe pinpoint what's slow and/or give some ideas on how to speed it up?
