The Node Capacitated Graph Partitioning Problem : A Computational Study

FERREIRA, Carlos E.; SOUZA, Cid C. de; MARTIN, Alexander; … - Center for Operations Research and Econometrics (CORE), … - 1994

In this paper we consider the problem of k-partitioning the nodes of a graph with capacity restrictions on the sum of the node weights in each subset of the partition, and the objective of minimizing the sum of the costs of the edges between the subsets of the partition. Based on a study of...

Preconditioning techniques for the solution of the Helmholtz equation by the finite element method

Kechroud, Riyad; Soulaimani, Azzeddine; Saad, Yousef; … - In: Mathematics and Computers in Simulation (MATCOM) 65 (2004) 4, pp. 303-321

This paper discusses 2D and 3D solutions of the harmonic Helmholtz equation by finite elements. It begins with a short survey of the absorbing and transparent boundary conditions associated with the DtN technique. The solution of the discretized system by means of a standard Galerkin or Galerkin...

On some aspects of the discontinuous Galerkin finite element method for conservation laws

Dolejší, Vít; Feistauer, Miloslav; Schwab, Christoph - In: Mathematics and Computers in Simulation (MATCOM) 61 (2003) 3, pp. 333-346

The paper is concerned with the numerical solution of nonlinear conservation laws and nonlinear convection–diffusion problems. We discuss two versions of this method: (a) Finite volume discontinuous Galerkin (FVDG) method, which is a generalization of the combined finite volume–finite...
