Simulation has become the evaluation method of choice for many areas of distributing computing research. However, most existing simulation packages have several limitations on the size and complexity of the system being modeled. Fine grained simulation of complex systems such as Grids requires high computational effort which can only be obtained by using an underlying distributed architecture. ...

One of the main drawbacks of NMPC schemes is the enormous computational effort these controllers require. On the other hand, linear MPC methods can be implemented solving just Quadratic Programming (QP) or Linear Programming (LP) problems. In this paper, an alternative implementation of NMPC suggested by De Keyser (1998) is implemented to reduce the computational effort. This methodology is bas...

The "magnetic force theorem" is frequently used to compute exchange interaction parameters and adiabatic spin-wave spectra of ferromagnets. The interest of this approach is that it allows one to obtain these results from a non-self-consistent calculation of the (single-electron) band energy only, which greatly reduces the computational effort. However, as discussed by various authors, this appr...

We propose a new approach to reach a near maximum likelihood (ML) MIMO detection performance with a strongly reduced computational effort. This method is based on a two-stage detection. In the first detection step a Zero-Forcing (ZF) equalizer is applied followed by a subsequent decision unit. The second step is a reduced-search (RS) algorithm over the ZF solution, which will be performed in an...

Reverse Engineering software packages are not able to automatically and robustly detect the sub-regions of a tessellated model; it generally results in a first trial subdivision which subsequently has to be refined, requiring a large amount of human intervention and high computational effort. To avoid these limitations, the authors propose a multilevel local approach for the automatic identific...

CCTV systems are broadly deployed in the present world. Despite this, the impact on anti-social and criminal behaviour has been minimal. Subject reacquisition is a fundamental task to ensure in-time reaction for intelligent surveillance. However, traditional reacquisition based on face recognition is not scalable, hence in this paper we use reasoning techniques to reduce the computational effor...

In everyday life, we have to decide whether it is worth exerting effort to obtain rewards. Effort can be experienced in different domains, with some tasks requiring significant cognitive demand and others being more physically effortful. The motivation to exert effort for reward is highly subjective and varies considerably across the different domains of behaviour. However, very little is known...

Abstract POPMUSIC is a template for creating heuristics specially designed for dealing with large combinatorial problems that can be partially optimized. The basic idea is to optimize sub-parts of solutions until a local optimum is reached. The useful computational effort should be spent for optimizing these sub-parts. However, it is observed in practice that this computational effort grows alm...

This article introduces a statistical approach for the maximization of the financial benefits yielded by software projects that have been broken down into a considerable number of minimum marketable features modules (MMFs) and architectural elements (AEs). As the statistical approach requires a polynomial computational effort to run and provides approximation solutions with an arbitrarily chose...
