Bounds on the Spectral Sparsification of Symmetric and Off-Diagonal Nonnegative Real Matrices
Sergio Mercado, Marcos Villagra
We say that a square real matrix is \emph{off-diagonal nonnegative} if and only if all entries outside its diagonal are nonnegative real numbers. In this note we show that for…
A Distributed Algorithm for Spectral Sparsification of Graphs with Applications to Data Clustering
Fabricio Mendoza-Granada, Marcos Villagra
Spectral sparsification is a technique that is used to reduce the number of non-zero entries in a positive semidefinite matrix with little changes to its spectrum. In particular, t…
Multiobjective Optimization in a Quantum Adiabatic Computer
Benjamin Baran, Marcos Villagra
In this work we present a quantum algorithm for multiobjective combinatorial optimization. We show how to map a convex combination of objective functions onto a Hamiltonian and the…
