Experiments demonstrate that randomized SDP rounding achieves the Goemans-Williamson 0.878 ratio for both max-cut and weighted fractional cut-covering simultaneously after only about 128 ln m samples, with LP post-processing yielding better certificates than the theoretical algorithm.

Maximum Cuts and Fractional Cut Covers: A Computational Study of a Randomized Semidefinite Programming Approach
Experiments demonstrate that randomized SDP rounding achieves the Goemans-Williamson 0.878 ratio for both max-cut and weighted fractional cut-covering simultaneously after only about 128 ln m samples, with LP post-processing yielding better certificates than the theoretical algorithm.
