An Optimal Index Reshuffle Algorithm for Multidimensional Arrays and Its Applications for Parallel Architectures

An Optimal Index for PAT Arrays

We study the problem of keeping in main memory an index for a large PAT array stored in secondary storage. This index is used to minimize the number of accesses to secondary memory, performing the main part of the search in main memory. However, we have a maximum allowed size for this index, and it is not clear which is the optimum between keeping many short keys or few long keys. We rst derive...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

An improved genetic algorithm for multidimensional optimization of precedence-constrained production planning and scheduling

Integration of production planning and scheduling is a class of problems commonly found in manufacturing industry. This class of problems associated with precedence constraint has been previously modeled and optimized by the authors, in which, it requires a multidimensional optimization at the same time: what to make, how many to make, where to make and the order to make. It is a combinatorial,...

A Differential Evolution Algorithm for Multidimensional Arrays

In this paper, we propose a differential evolution (DE) algorithm which aims to optimize a system whose parameters form a multidimensional array. Determination of the optimal demixing matrix in a blind signal separation problem can be considered as an example of this type of system. Since the DE algorithm performs only on column vectors, it can be used after the multidimensional array is transf...
