Vochysia divergens Pohl (Vochysiaceae) is a tree commonly found in wet soils of 'Pantanal' of Mato Grosso, Brazil, and used in folk medicine against infections and asthma. We have studied differentâ€¦ (More)

A heuristic for the Maximum Clique Problem was parallelized on a Graphical Processing Unit and a cluster of workstations. The heuristic is based on a formulation based on neural networks. Performanceâ€¦ (More)

In the current chemical literature, a large number of vertexâ€“degreeâ€“based topological indices TI are considered, defined as the sum over all edges of the molecular graph of some function Î¨(x, y),â€¦ (More)

We find an upper bound for the number of bay regions over the set of hexagonal systems with h hexagons. We also determine extremal values of vertex-degree based topological indices over the set ofâ€¦ (More)

An algorithm to find the maximal clique on an interval graphs was parallelized on Graphical Processing Units. The algorithm was implemented using CUDA and the Thrust library. Performance results areâ€¦ (More)

We show that the zig-zag chain Z3 n of segments of length 3 (see Figure 2) has the minimal ABC index among all polyomino chains with n squares. More generally, we give conditions on the numbers {Ï†ij}â€¦ (More)
