Is it possible to disable the implicit factor of 0.5 in the optimization objectives quadratic part?
Through trial and error, I figured out, that the XPress optimizer is using an implicit factor of 0.5 in the quadratic part of the optimization objective (which doesn't show up in the mps dumps btw.) ...
Hi Imre,
I read this part of the documentation, but cannot make sense out of it: The first sentence claims, there is an exception, for rows of type L or G, but then the second sentence doesn't seem to explain the exception and is rather concerned about rows of type N instead.
Anyway, I can confirm, that using the objective transfer variable works and doesn't include the implicit factor of 0.5.
