Distributed Linear Programming on GPU Clusters at Extreme Scale
Arnaud Deza, Santanu Dey, Pascal Van Hentenryck
Large linear programs can exceed the memory of a single compute node. Although first-order methods replace sparse factorizations with GPU-suited matrix-vector products, other solve…
Decomposition of Sparse Integer Programs via Nonlinear Edge Encodings and Column-and-Row Generation
Gustavo Angulo, Santanu S. Dey
A wide range of sparse integer programs admit a block structure in which subproblems interact through a small set of shared variables. Dualizing the linking equalities yields a dec…
The Skew Commutators of Toeplitz and Hankel operators in vector-valued Hardy Space
Priyanka Aroda, Santanu Dey
In this article, we characterize when a Toeplitz operator and a Hankel operator on the vector-valued Hardy space are skew commutators of each other, and determine necessary and suf…
Non-Monotonicity of Branching Rules with respect to Linear Relaxations
Prachi Shah, Santanu S. Dey, Marco Molinaro
Modern mixed-integer programming solvers use the branch-and-cut framework, where cutting planes are added to improve the tightness of the linear programming (LP) relaxation, with t…
A reformulation-enumeration MINLP algorithm for gas network design
Yijiang Li, Santanu S. Dey, Nikolaos V. Sahinidis
Gas networks are used to transport natural gas, which is an important resource for both residential and industrial customers throughout the world. The gas network design problem is…
Characteristic Functions and Colligations
Neeru Bala, Santanu Dey, Kalpesh J. Haria +1
The characteristic function of row contractions and the characteristic function of liftings of row contractions are multi-analytic operators which are complete invariants up to uni…
