Two-Hop Virtual Path Layout in Tori
We consider a problem motivated by the design of ATM (Asynchronous Transfer Mode) networks. Given a physical network and an All-to-All traffic, the problem consists in designing a...

Complexity dichotomy on degree-constrained VLSI layouts with unit-length edges
Deciding whether an arbitrary graph admits a VLSI layout with unit-length edges is NP-complete [1], even when restricted to binary trees [7]. However, for certain graphs, the prob...

Optimal Sensor Network Layout Using Multi-Objective Metaheuristics
: Wireless Sensor Networks (WSN) allow, thanks to the use of small wireless devices known as sensor nodes, the monitorization of wide and remote areas with precision and liveness u...

Increasing the readability of graph drawings with centrality-based scaling
A common problem in visualising some networks is the presence of localised high density areas in an otherwise sparse graph. Applying common graph drawing algorithms on such networ...

Two-stage general block patterns for the two-dimensional cutting problem
This paper presents an algorithm for the unconstrained two-dimensional cutting problem of rectangular pieces. It proposes the two-stage general block pattern that can be cut into ...
