Mixed-Integer Convex Programming: Branch-and-bound with Frank-Wolfe-based convex relaxations
Otherwise the problem is completely fixed
Use SCIP reoptimization option at the root node. This should be tested first in SCIP itself. There are problems with setting this parameter on our end.
I created a MPS file with the lmo. If you read in the file and change the objective the warning does not appear. However, if you create the lmo by...
Where does this warning come from? See below. Run is for `n = 5`, `k = 2`. ``` julia> include("examples/birkhoff.jl") seed = 0x6a330cff07fe872a WARNING: redefinition of constant Xstar. This may...
What can we say about the problem before solving? Can this information speed up the solution process?
Propagate information about the problem from Boscia to the MIP solver. For example, conflicts.
Could this improve the progress of the lower bound?
This pull request sets the compat entry for the `DoubleFloats` package to `1`. This keeps the compat entries for earlier versions. Note: I have not tested your package with this...

It can be more useful in some cases to solve the LP in Frank-Wolfe not the MIP (see Network Design Problem). We currently rely a lot on the fact that...
