In this paper, we propose a new sweep coverage problem: The Minimum Capacitated Sweep Cover (MinCapSC) problem, the goal of which is to design routes for the minimum number of mobile sensors such t ...

Abstract In this study, novel Hyperbolic spinor sequences of Jacobsthal, Jacobsthal–Lucas and Jacobsthal polynomial, which have not been studied before, are defined by investigating the relationship ...

Have you ever wondered, how to compute outside a computer? The Handbook of Unconventional Computing (In 2 Volumes), edited by Professor Andrew Adamatzky, offers unconventional ways of thinking about ...

Distinct points create the distance and comparison, and also everyone in this world is trying to minimize distance in one’s sense. Therefore, the real-life problem may be converted mathematically i ...

Abstract Denote by τ k (n), ω (n) and μ 2 (n) the number of representations of n as a product of k natural numbers, the number of distinct prime factors of n and the characteristic function of the ...

For an integer k ≥ 2, a k-tree T is defined to be a tree T with maximum degree at most k. If a k-tree T spans a graph G, then T is called a spanning k-tree of G. Since a spanning 2-tree is a Hamilt ...

The concept of matchings originated in group theory to address a linear algebra problem related to canonical forms for symmetric tensors. In an abelian group (G, +), a matching is a bijection f : A ...
