Does warm starting DAQP MIQP BnB work? #185

Description

@nurkanovic

Hi,

I am wondering is it possible to provide a warm start to DAQP BnB?
In my application, I have almost always an integer feasible guess, but I noticed that the timing does not change if I actually pass it to DAQP.

use DAQP via CasADi's conic, which is possible since the latest 3.8.0. release (and not directly via its python interface).
I do not know is it an issue on the CasADi interface side or does DAQP not accept the binary to prune the BnB tree?

Regarding the former, if I pass a warm start to gurobi via CasADi's conic, it gets accepted and I do see an significant improvement in computation times.

Thanks!
