Webfourth marginal moments exactly (instead of matching all third and fourth marginal moments approximately, as in [8]). However, the computational sim-plicity as well as stability of results demonstrated in this paper arguably out-weigh this shortcoming.

Persistence in discrete optimization under data uncertainty

Webdiscrete optimization problems to find the persistency.Another complicating factor that arises in applications is often the incomplete knowledge of distributions (cf. [4]). In this paper, we formulate a parsimonious model to compute the persistency, by specifying only the range and marginal moments of each. c ˜ i. in the objective function. WebOptimization with Marginals and Moments. Optimization with Marginals and Moments discusses problems at the interface of optimization and probability. Combining optimization and probability leads to computational challenges. At the same time, it allows us to model a large class of planning problems. Webgiven marginal moment information. 1.2. Contributions. In this paper, building on the work of Bertsimas and Popescu [4] connecting moment problems and semidefinite optimization, we gener-alize the approach by Meilijson and Nadas [21] and develop techniques to compute Z∗ max and Z∗ min for general 0-1 optimization problems.
