A vertex-colored graph is rainbow vertex-connected if any two vertices are connected by a path whose internal vertices have distinct colors, which was introduced by Krivelevich and Yuster. Theâ€¦ (More)

The general RandiÄ‡ index RÎ±(G) of a (chemical) graph G, is defined as the sum of the weights (d(u)d(v))Î± of all edges uv of G, where d(u) denotes the degree of a vertex u in G and Î± an arbitrary realâ€¦ (More)

The concept of rainbow connection was introduced by Chartrand et al. in 2008. It is fairly interesting and recently quite a lot papers have been published about it. In this survey we attempt to bringâ€¦ (More)

Many graph invariants have been used for the construction of entropy-based measures to characterize the structure of complex networks. Based on Shannonâ€™s entropy, we study graph entropies which areâ€¦ (More)

This paper demonstrates methods for the online optimization of assistive robotic devices such as powered prostheses, orthoses and exoskeletons. Our algorithms estimate the value of a physiologicalâ€¦ (More)

A molecular (n,m)-graph G is a connected simple graph with n vertices, m edges and vertex degrees not exceeding 4. If d(v) denotes the degree of the vertex v , then the zeroth-order general RandiÄ‡â€¦ (More)

OBJECTIVE
Multivariate data sets often differ in several factors or derived statistical parameters, which have to be selected for a valid interpretation. Basing this selection on traditionalâ€¦ (More)
