On Generating Lagrangian Cuts for Two-Stage Stochastic Integer Programs
Rui Chen, James Luedtke
We investigate new methods for generating Lagrangian cuts to solve two-stage stochastic integer programs. Lagrangian cuts can be added to a Benders reformulation, and are derived f…
Multilinear Sets with Two Monomials and Cardinality Constraints
Rui Chen, Sanjeeb Dash, Oktay Gunluk
Binary polynomial optimization is equivalent to the problem of minimizing a linear function over the intersection of the multilinear set with a polyhedron. Many families of valid i…
Theta Correspondence and Arthur packets
Rui Chen, Jialiang Zou
In spirit of Gan-Ichino's work on the Arthur's multiplicity formula for metaplectic groups, we have established the Arthur's multiplicity formula for even orthogonal or unitary gro…
Arthur's multiplicity formula for even orthogonal and unitary groups
Rui Chen, Jialiang Zou
Let G be an even orthogonal or unitary group over a number field. Based on the same observation used in arXiv:1705.10106, we prove the Arthur's multiplicity formula for the generic…
Integer Programming for Causal Structure Learning in the Presence of Latent Variables
Rui Chen, Sanjeeb Dash, Tian Gao
The problem of finding an ancestral acyclic directed mixed graph (ADMG) that represents the causal relationships between a set of variables is an important area of research on caus…
