CS 598 CSC : Approximation
In the last lecture a primal-dual analysis was used to show a 2-approximation for theVertex Cover problem. Here we extend these ideas to show a 2-approximation for the Steiner Forest problem using a primal-dual analysis. In the Steiner Forest problem there is a graph G = (V,E) where each edge e ∈ E has a cost ce ∈ R. We are given k pairs of terminals s1, t1, s2, t2, . . . sk, tk ∈ V . The goal ...

In the previous class, we had looked at the RMW algorithm. In this setting, the actions/decisions are referred to as experts. Assume that we have N experts. On any given day t, we choose an expert to use from among the N experts (like choosing a function h ∈ H). The adversary/world returns a loss vector lt = (lt 1, · · · lt N ). If the expert it is chosen on day t, then the performance after T ...

The aim of this study was to investigate changes in serum cytokine levels in children with handfoot-and-mouth disease (HFMD) and their clinical significance. Clinical data from 241 children with HFMD, hospitalized between May 2012 and January 2013, were analyzed retrospectively. Patients were divided into a normal case group (n=107) and a severe case group (n=134), and the clinical features of ...

Credit Market Constraints and Labor Market Decisions In this paper, we examine whether imperfections in credit markets spill over to other markets, particularly the labor market. We take the case of Italy, a country that experienced changes in the mortgage market brought about by the 1992 European unification and other institutional shifts. These events make Italy a good laboratory to study the...

In the last lecture, we were looking at clustering sparse graphs in the stochastic block model with parameters p > q, where p = a n , and q = b n , we saw that we could not do perfect clustering as w.h.p, there will be a constant fraction of isolated vertices. However, we shall see that we can still do weak recovery, i.e., by allowing a small fraction of vertices to be misplaced, we will recove...
