A few questions:
(1) Can CBC be 'warm-started' with a full and/or partial MILP solution?
For things like red-cost fixing, fathoming, etc. If so, how?
(2) Can CBC be given a starting upper bound (for a minimization)? i.e.,
(1) w/o the actual solution, just the bound.
(3) Can (1) and (2) be done through the OsiCbc / any Osi interface?
(4) I am pretty sure Cplex can do (1) and (2), how would one do this
through the OsiCpx interface?
(5) Where can I find a list of Cbc (library) parameters and what they
do? I suspect, if (2) is possible, it is just a parameter - but I am not
sure where I find that - I checked CbcParam.hpp but there are no
descriptions.
Thanks,
Matt
