WebFeb 9, 2024 · To benchmark the performance of the XQAOA ansatz at low depth, we derive its closed-form expression for the MaxCut problem and compare it to QAOA, Multi-Angle QAOA (MA-QAOA), a Classical-Relaxed (CR) algorithm, and the state-of-the-art Goemans-Williamson (GW) algorithm on a set of unweighted regular graphs with 128 and 256 … Webc) In the experiments on maxcut (table 2), the authors have selected 6 graphs from the Helmberg and Rendl set of 24 weighted graphs. These are toroidal graphs, which have a known upper bound on the cut size.
