coupling swmmr with dream algorithm

[Zhassan1]

Hi Leutnant
I am thinking to couple of SWMM model with the DREAM algorithm (like you have already written code for the DREAM algorithm in R for auto-calibration of SWMM. I have an intermediate level skills of R. Is it possible to do that? Another question is about the multiobjective algorithm which you have written in R for autocalibration. Up to how many parameters normally I can use to calibrate.I have a urban model with almost 300 sub-catchments. I will be happy to know about its performance for large catchments?

Thanks

Coupling DREAM with swmmr is definitely doable and would be of high interest to me and most probably to other swmmr's as well. Is there a stable DREAM algorithm for R available?
Calibrating a model using a multiobjective strategy is from the "implementation" perspective comparable to a single-objective one. You generally deal with matrices instead of vectors. I used the NSGA-II from mco.

Up to how many parameters...?

Well, I reckon this cannot be answered in general as it heavily depends on the complexity of your model and the corresponding objective function.
