This article describes the development of a new intelligent heuristic search algorithm (IHSA * ) which guarantees an optimal solution for flow-shop problems with an arbitrary number of jobs and machines provided the job sequence is constrained to be the same on each machine. The development is described in terms of 3 modifications made to the initial version of IHSA * . The first modification c...

Power System Stabilizers (PSS) are generally employed to damp electromechanical oscillations by providing auxiliary stabilizing signals to the excitation system of the generators. But it has been found that these Conventional PSS (CPSS) do not provide sufficient damping for inter-area oscillations in multimachine power systems. Thyristor Controlled Series Capacitor (TCSC) has immense potential ...

The laboratory rat has been used as a surrogate to study human biology for more than a century. Here we present the first genome-scale network reconstruction of Rattus norvegicus metabolism, iRno, and a significantly improved reconstruction of human metabolism, iHsa. These curated models comprehensively capture metabolic features known to distinguish rats from humans including vitamin C and bil...

This paper addresses the close-open mixed vehicle routing problem (COMVRP) that both close and open variants of the vehicle routing problem are simultaneously considered. The objective is to find the solution which minimizes the total cost of delivery. In this paper, we propose an improved harmony search algorithm (IHSA) composed of two main approaches. First, the probabilistic Clarke-Wright sa...

For the entire Islamic tradition, the crowning glory of Aristotelian logic is the syllogistic theory outlined in the Prior and Posterior Analytics, especially the latter. The purpose of logic is to provide the means whereby knowledge is to be acquired, and the most valuable type of knowledge is that which is certain and necessary, that is, knowledge gained according to the paradigm of demonstra...

We prove that IHSA, the theory of infinite dimensional Hilbert spaces equipped with a generic automorphism, is א0-stable up to perturbation of the automorphism, and admits prime models up to perturbation over any set. Similarly, APrA, the theory of atomless probability algebras equipped with a generic automorphism is א0-stable up to perturbation. However, not allowing perturbation it is not eve...

This article presents an intelligent heuristic search algorithm (IHSA*) for solving flow-shop problems with two or three machines and an arbitrary number of jobs. Following its initial development the algorithm has been modified in two different ways in order to reduce backtracking and to improve its performance. The first modification concerns the choice of the best heuristic function to use, ...
