... correspond to a divergence of some of the values of P l (i) (k). However, a rigorous proof of such a divergence is complicated by the interactive nature of the iterations of (6) and (9). As long as ... 2: Illustration of P l (i) (k) of the DCLS algorithm with K = 3 and λ = 5 for the ring network versus the iteration index i for an arbitrary choice of l and k and di...
