Maximizing the Smallest Eigenvalue of a Symmetric Matrix: A Submodular Optimization Approach
Andrew Clark, Qiqiang Hou, Linda Bushnell +1
This paper studies the problem of selecting a submatrix of a positive definite matrix in order to achieve a desired bound on the smallest eigenvalue of the submatrix. Maximizing th…
On the Structure and Computation of Random Walk Times in Finite Graphs
Andrew Clark, Basel Alomair, Linda Bushnell +1
We consider random walks in which the walk originates in one set of nodes and then continues until it reaches one or more nodes in a target set. The time required for the walk to r…
