Variational Theory and Algorithms for a Class of Asymptotically Approachable Nonconvex Problems
Hanyang Li, Ying Cui
We investigate a class of composite nonconvex functions, where the outer function is the sum of univariate extended-real-valued convex functions and the inner function is the limit…
The Minimization of Piecewise Functions: Pseudo Stationarity
Ying Cui, Junyi Liu, Jong-Shi Pang
There are many significant applied contexts that require the solution of discontinuous optimization problems in finite dimensions. Yet these problems are very difficult, both compu…
On Efficient and Scalable Computation of the Nonparametric Maximum Likelihood Estimator in Mixture Models
Yangjing Zhang, Ying Cui, Bodhisattva Sen +1
In this paper we study the computation of the nonparametric maximum likelihood estimator (NPMLE) in multivariate mixture models. Our first approach discretizes this infinite dimens…
A Decomposition Algorithm for Two-Stage Stochastic Programs with Nonconvex Recourse
Hanyang Li, Ying Cui
In this paper, we have studied a decomposition method for solving a class of nonconvex two-stage stochastic programs, where both the objective and constraints of the second-stage p…
Nonconvex and Nonsmooth Approaches for Affine Chance-Constrained Stochastic Programs
Ying Cui, Junyi Liu, Jong-Shi Pang
Chance-constrained programs (CCPs) constitute a difficult class of stochastic programs due to its possible nondifferentiability and nonconvexity even with simple linear random func…
On Degenerate Doubly Nonnegative Projection Problems
Ying Cui, Ling Liang, Defeng Sun +1
The doubly nonnegative (DNN) cone, being the set of all positive semidefinite matrices whose elements are nonnegative, is a popular approximation of the computationally intractable…
