Chain Hexagonal Cacti with the Extremal Eccentric Distance Sum
Eccentric distance sum (EDS), which can predict biological and physical properties, is a topological index based on the eccentricity of a graph. In this paper we characterize the chain hexagonal cactus with the minimal and the maximal eccentric distance sum among all chain hexagonal cacti of length n, respectively. Moreover, we present exact formulas for EDS of two types of hexagonal cacti.
متن کاملThe number of matchings of low order in hexagonal systems
A simple way to calculate the number of k-matchings, k ~< 5, in hexagonal systems is presented. Some relations between the coefficients of the characteristic polynomial of the adjacency matrix of a hexagonal system and the number of matchings are obtained. (~) 1998 Elsevier Science B.V.

متن کاملZ-transformation graphs of perfect matchings of hexagonal systems
Let H be a hexagonal system. The Z-transformation graph Z(H) is the graph where the vertices are the perfect matchings of H and where two perfect matchings are joined by an edge provided their symmetric difference is a hexagon of H (Z. Fu-ji et al., 1988). In this paper we prove that Z(H) has a Hamilton path if H is a catacondensed hexagonal system. A hexagonal system [ll], also called honeycom...
متن کاملChain hexagonal cacti: extremal with respect to the eccentric connectivity index
In this paper we present explicit formulas for the eccentric connectivity index of three classes of chain hexagonal cacti. Further, it is shown that the extremal chain hexagonal cacti with respect to the eccentric connectivity index belong to one of the considered types. Some open problems and possible directions of further research are mentioned in the concluding section.
متن کاملCacti 4.0
The original CACTI tool was released in 1994 to give computer architects a fast tool to model SRAM caches. It has been widely adopted and used since. Two new versions were released to add area and active power modeling to CACTI. This new version adds a model for leakage power and updates the basic circuit structure and device parameters to better reflect the advances in scaling semiconductors w...
