Detailed Description

fractional rounding heuristic for SDPs

Author

Marc Pfetsch

Fractional rounding heuristic for SDPs: Takes the solution of the SDP-relaxation and iteratively rounds all integer variables. After each rounding the problem is propagated. If the SDP includes continuous variables, the remaining SDP after the fixings is solved again.
