Webb10 apr. 2024 · Therefore, there is a polynomial time algorithm for finding weighted maximum cuts, with high probability, when the input is drawn from \(\overline{{\mathcal G}}_{n, n, \frac{c}{n}}\), with \(c<1\). We believe that this part of our work may also be of interest regarding the design of efficient algorithms for finding minimum disrepancy … WebbIn this paper, we investigate how to compute the throughput of probabilistic and replicated streaming applications. We are given (i) a streaming application whose dependence graph is a linear chain; (ii) a one-to-many mapping of the application onto a fully heterogeneous target, where a processor is assigned at most one application stage, but where a stage …
