Optimal Search on Clustered Structural Constraint for Learning Bayesian Network Structure
We study the problem of learning an optimal Bayesian network in a constrained search space; skeletons are compelled to be subgraphs of a given undirected graph called the super-st...

An Algorithm to List All the Fixed-Point Free Involutions on a Finite Set
A fixed-point free involution on a finite set S is defined as a bijection I : S S such as e S, I(I(e)) = e and e S, I(e) = e. In this article, the fixed-point free involutions ...

An optimal randomized algorithm for maximum Tukey depth
We present the first optimal algorithm to compute the maximum Tukey depth (also known as location or halfspace depth) for a non-degenerate point set in the plane. The algorithm is...
