Goemans williamson algorithm
WebWilliamson [10], PCST is a Lagrangian relaxation of the k-MST problem, which asks for the minimum-cost tree spanning at least k nodes. Moreover, they note that the PCST algorithm of Goemans and Williamson (henceforth called GW ) is not just a 2-approximation algorithm, but also a Lagrangian preserving 2-approximation (we give a WebHere, we demonstrate that the Loihi platform is capable of effectively implementing the Goemans-Williamson (GW) approximation algorithm for MAXCUT, an NP-hard …
