WebSolving (1) is difficult because the problem is nonconvex and nondifferentiable, especially for a large-scale network of agents. 3 Convex Relaxation Problem (1) is nonconvex in both the distance and angle terms. We follow the relaxation proposed in [31], which we restate in this section, before extending it with velocity measurements. northern star potato chaska mnWebRoughness down to atomic and close-to-atomic scale is receiving an increasing attention in recent studies of manufacturing development, which can be realized by high-precision polishing processes.
