Polymatroids and mean-risk minimization in discrete optimization
We study discrete optimization problems with a submodular mean-risk minimization objective. For 0-1 problems a linear characterization of the convex lower envelope is given. For mi...

Optimal Transportation Problem by Stochastic Optimal Control
We solve optimal transportation problem using stochastic optimal control theory. Indeed, for a super linear cost at most quadratic at infinity, we prove Kantorovich duality theore...

An Inverse Power Method for Nonlinear Eigenproblems with Applications in 1-Spectral Clustering and Sparse PCA
Many problems in machine learning and statistics can be formulated as (generalized) eigenproblems. In terms of the associated optimization problem, computing linear eigenvectors a...

A Prototype for Multiple Whole Genome Alignment
In this paper, we briefly describe a prototype of the software system we have developed for multiple whole genome alignment. To develop our algorithm, we have to solve several pr...
