The bandwidth, average bandwidth, envelope, profile and antibandwidth of the matrices
have been the subjects of study for at least 45 years. These problems have generated …

This work proposes proposed a technique inspired by memetic algorithm (MA) to improve
the convergence of iterative methods for solving systems of equations. In the first phase the …

This paper presents some experimental results obtained on a parallel computer IBM Blue
Gene/P that shows the average bandwidth reduction [11] relevance in the serial and parallel …

This chapter refers to the use of Brain Storm Optimization (BSO) algorithms in solving
equations systems (ES). BSO algorithm is a swarm intelligence algorithm, which simulates …

Brain storm optimization (BSO) algorithm is a swarm intelligence algorithm, which simulates
the human brainstorming process. This paper proposes two hybrid methods based on BSO …

This paper proposes a parallel hybrid heuristic aiming the reduction of the bandwidth of
sparse matrices. Mainly based on the geometry of the matrix, the proposed method uses a …

This paper proposes two parallel hybrid heuristics aiming for the reduction of the average
bandwidth of sparse matrices, process used in systems of equations preconditioning. Based …

In solving systems of equations on parallel computers, one very important problem is load
balancing, because this affects the process efficiency. One way of achieving this goal is a …
