Optimal strategies for equal-sum dice games
In this paper we consider a non-cooperative two-person zero-sum matrix game, called dice game. In an (n, ) dice game, two players can independently choose a dice from a collection...

Maximizing breaks and bounding solutions to the mirrored traveling tournament problem
We investigate the relation between two aspects of round robin tournament scheduling problems: breaks and distances. The distance minimization problem and the breaks maximization ...

Approximating the minimum clique cover and other hard problems in subtree filament graphs
Subtree filament graphs are the intersection graphs of subtree filaments in a tree. This class of graphs contains subtree overlap graphs, interval filament graphs, chordal graphs,...

Two-tuple balance of non-binary sequences with ideal two-level autocorrelation
Let p be a prime, q = pm and Fq be the finite field with q elements. In this paper, we will consider q-ary sequences of period qn - 1 for q > 2 and study their various balance ...

On the structure of the adjacency matrix of the line digraph of a regular digraph
We show that the adjacency matrix M of the line digraph of a d-regular digraph D on n vertices can be written as M = AB, where the matrix A is the Kronecker product of the all-one...

On error-tolerant DNA screening
Given n clones with some positive ones, the problem of DNA screening is to identify all positive clones with a set of tests each on a subset of clones, called a pool and the outco...
