The vibration pattern of a rotor system reflects the mechanical parameter changes in the system. Hence, the use of vibration monitoring is considered as a possible means of detecting the presence and growth of the cracks. In this paper, a pattern search based method for shaft cra
COST OPTIMIZATION OF STEEL-CONCRETE COMPOSITE I-GIRDER BRIDGES WITH SKEW ANGLE AND LONGITUDINAL SLOPE, USING THE SM TOOLBOX AND THE PARALLEL PATTERN SEARCH ALGORITHM
In this research, the optimization problem of the steel-concrete composite I-girder bridges is investigated. The optimization process is performed using the pattern search algorithm, and a parallel processing-based approach is introduced to improve the performance of this algorit
Pattern Search Algorithms for Surface Wave Analysis
In recent years Rayleigh waves have been used increasingly as a nondestructive tool to obtain near-surface S-wave velocity, one of the key parameters in environmental and engineering applications (Miller et al., 1999a, 1999b; Park et al., 1998, 1999; Xia et al., 1999, 2003; Foti
Rank Ordering and Positive Bases in Pattern Search Algorithms
Abstract. We present two new classes of pattern search algorithms for unconstrained minimization: the rank ordered and the positive basis pattern search methods. These algorithms can nearly halve the worst case cost of an iteration compared to the classical pattern search algorit
Precision Control for Generalized Pattern Search Algorithms with Adaptive Precision Function Evaluations
In the literature on generalized pattern search algorithms, convergence to a stationary point of a once continuously differentiable cost function is established under the assumption that the cost function can be evaluated exactly. However, there is a large class of engineering pr
A Novel Adaptive Rood Pattern Search Algorithm
This paper is based upon Adaptive Rood Pattern Search algorithm for Block Matching Algorithm. There are various types of algorithm is available but this method is most reliable. Experimental results shows that it gives better results than other algorithms. This algorithm uses mot
Convergence Results for Generalized Pattern Search Algorithms are Tight
The convergence theory of generalized pattern search algorithms for unconstrained optimization guarantees under mild conditions that the method produces a limit point satisfying first order optimality conditions related to the local differentiability of the objective function. By
Locally-Adaptive and Memetic Evolutionary Pattern Search Algorithms
Recent convergence analyses of evolutionary pattern search algorithms (EPSAs) have shown that these methods have a weak stationary point convergence theory for a broad class of unconstrained and linearly constrained problems. This paper describes how the convergence theory for EP
Second Order Behavior of Pattern Search Algorithms
Abstract: Previous analyses of pattern search algorithms for unconstrained and linearly constrained minimization have focused on proving convergence of a subsequence of iterates to a limit point satisfying either directional or first-order necessary conditions for optimality, dep
On the Convergence of Mixed Integer Pattern Search Algorithms
The deenition of pattern search methods for solving nonlinear uncon-strained optimization problems is generalized here to include integer variables. We present a generalized pattern search algorithm that provides an accumulation point having a null gradient with respect to the co
