A lower bound on the average number of Pivot-steps for solving linear programs Valid for all variants of the Simplex-Algorithm

Borgwardt, Karl Heinz; Huhn, Petra - In: Mathematical Methods of Operations Research 49 (1999) 2, pp. 175-210

In this paper we derive a lower bound on the average complexity of the Simplex-Method as a solution-process for linear programs (LP) of the type:<Equation ID="Equ1"> <EquationSource Format="TEX"/> </Equation> We assume these problems to be randomly generated according to the Rotation-Symmetry-Model: *Let a <Subscript>1</Subscript>,…,a <Subscript>m</Subscript>, v be distributed independently,...</subscript></subscript></equation>

GA-based fuzzy logic control of a solar power plant using distributed collector fields

Luk, P.C.K.; Low, K.C.; Sayiah, A. - In: Renewable Energy 16 (1999) 1, pp. 765-768

A novel genetic algorithm (GA) based fuzzy logic control (FLC) system has been developed for the solar power plant, Plataforma Solar de Almería (PSA) at Tabernas, in Almería, Spain. The rule base encompasses an empirical set of 49 “if-then” rules. Chromosomes consisting of 49 genes of...

Manipulator visual servoing and tracking of fish using a genetic algorithm

Minami, Mamoru; Agbanhan, Julien; Asakura, Toshiyuki - In: Industrial Robot: An International Journal 26 (1999) 4, pp. 278-289

This paper presents the real‐time visual servoing of a manipulator and its tracking strategy of a fish, by employing a genetic algorithm (GA) and the unprocessed gray‐scale image termed here as “raw‐image”. The raw‐image is employed to shorten the control period, since it has more...
