Hi,
Since I implemented the interface for Cbc to ECLiPSe, let me add a few
more details:
1. The specific message Ulrich is referring to is defined in
CbcMessage.cpp, and it seems to be given a detail level of 1, i.e. it
will be printed when the detail level for the MessageHandler is set to 1
(minimal). This is what I set all the MessageHandler to, the idea is
that only the most important messages should be passed to the user.
Should this message be set at this detail level?
2. I don't know what the exact conditions for generating this message
is. However, Cbc's branchAndBound() is only called if there are integer
variables in the original problem. I assume it is possible for pre-solve
to remove such integer columns -- would this be the situation where the
message is generated?
Cheers,
Kish
