Description
We discuss outer approximation based approaches to solve mixed
integer second order cone programming problems. These methods utilize a linear
outer approximation to derive integer assignments that are then used to solve
the corresponding continuous second order cone problems. The derived solution
is again used to strengthen the approximation. Results for the case of mixed
integer nonlinear programs with continuously differentiable constraint
functions can be extended to guarantee convergence of this approach under
similar assumptions. We show how this method can be sped up significantly by
exploiting the symmetric structure of a particular class of mixed 0-1 second
order cone problems. A computational study based on application problems is
provided.
