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 ...
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 ...
Abstract In this paper, we study on double domination (γ d) and double edge-vertex domination (γ dev) of trees. We obtain that determining the double e v -domination number is NP-complete for ...
Abstract Coded caching is an important method to alleviate network congestion during the peak period of network traffic, so it has been widely used in various network environments. Subpacketization ...
