A linear time algorithm to compute vertices that belong to all, some and no minimum dominating sets in a tree and its consequences [PDF]

open access: yesOpuscula Mathematica
We provide a linear time algorithm for determining the sets of vertices that belong to all, some and no minimum dominating sets of a tree, respectively, thus improving the quadratic time algorithm of Benecke and Mynhardt in 2008 [S.

Parameterized shifted combinatorial optimization [PDF]

open access: yesJournal of Computer and System Sciences, 2017
Shifted combinatorial optimization is a new nonlinear optimization framework which is a broad extension of standard combinatorial optimization, involving the choice of several feasible solutions at a time. This framework captures well studied and diverse problems ranging from so-called vulnerability problems to sharing and partitioning problems.
