Yet another algorithm for dense max cut: go greedy


We study dense instances of MaxCut and its generalizations. Following a long list of existing, diverse and often sophisticated approximation schemes, we propose taking the na&#239;ve greedy approach; we prove that when the vertices are considered in random order, our algorithms are still approximation schemes. Our algorithms may be simple, but the analysis is not. It relies on smoothing the vertices defining the partial cuts and on proving certain martingale properties. We also give a simpler proof of the result from Alon, Fernandez de la Vega, Kannan, and Karpinski [1] that dense problems have sample complexity &#213; (1/&#949;<sup>4</sup>). Like previous work, our results generalize to dense maximum constraint satisfaction problems.
