This paper discusses the implementation of the sparse matrix support with Octave. It address the algorithms that have been used, their implementation, including examples of using sparse matrices in scripts and in dynamically linked code. The octave sparse functions the compared with their equivalent functions with Matlab, and benchmark timings are calculated.

This paper presents a new operation (exorlink) and an algorithm to minimize Exclusive-OR Sum-of-Products expressions (ESOP’s) for multiple valued input, two valued output, incompletely specified functions. Exorlink is a more powerful operation than any other existing one for this problem. Evaluation on benchmark functions is given and it proves the superiority of the program to those known from...

In this paper, the Intelligent Water Drops (IWD) algorithm is augmented with a mutation-based local search to find the optimal values of numerical functions. The proposed algorithm called the IWD-CO (IWD for continuous optimization) is tested with six different benchmark functions. The experimental results are satisfactory, which encourage further researches in this regard. © 2011 Published by ...

data envelopment analysis (dea) with considering the best condition for each decision making unit (dmu) assesses the relative efficiency for it and divides a homogenous group of dmus in to two categories: efficient and inefficient, but traditional dea models can not rank efficient dmus. although some models were introduced for ranking efficient dmus, franklin lio & hsuan peng (2008), proposed a...

in this paper, a new continuous ant colony optimization (caco) algorithm is proposed for optimal reservoir operation. the paper presents a new method of determining and setting a complete set of control parameters for any given problem, saving the user from a tedious trial and error based approach to determine them. the paper also proposes an elitist strategy for caco algorithm where best solut...

This paper proposes a comprehensive approach on automatic optimisation of B-spline based neuro-fuzzy models. The underlying structure of a system decided by the displacements of the membership functions is an important factor for its generalisation ability and output accuracy. Therefore a genetic algorithm is introduced which is used to find a suitable model for an arbritrary given problem. App...
