the cuckoo search algorithm is a recently developedmeta-heuristic optimization algorithm, which is suitable forsolving optimization problems. to enhance the accuracy andconvergence rate of this algorithm, an improved cuckoo searchalgorithm is proposed in this paper. normally, the parametersof the cuckoo search are kept constant. this may lead todecreasing the efficiency of the algorithm. to cop...

this research provides an optimization tool for use by supply chain managers in the design and operation of manufacturing- distribution networks under uncertain demand conditions. the problem under consideration consists of determining the supply chain infrastructure; raw material purchases, shipments, and inventories; and finished product production quantities, inventories, and shipments neede...

there are a lot of approximation techniques for structural optimization. among them, four outstanding approximation methods have been selected for trusses optimization. these approaches have been developed or modified by previous ones. based on these schemes, a lot of trusses have been optimized by author's program. this study shows that the abilities of the mentioned methods are not the s...

This lecture deals with the application of numerical optimization for aerodynamic design of high-lift systems, which is a multi-objective constraint design problem. The applied mathematical fundamentals of numerical optimization are briefly outlined. A description of the design targets and constraints for high-lift wings is given, followed by a detailed analysis of the properties of the flow ca...

The teaching–learning-based optimization algorithm (TLBO) is an efficient optimizer. However, it has several shortcomings such as premature convergence and stagnation at local optima. In this paper, the strengthened (STLBO) proposed to enhance basic TLBO’s exploration exploitation properties by introducing three strengthening mechanisms: linear increasing teaching factor, elite system composed ...

In this paper, optimization of the sound transmission loss of finite rectangular anisotropic laminated composite plate with simply supported boundary conditions has been developed to maximize transmission loss. Appropriate constraints were imposed to prevent the occurrence of softening effect due to optimization. For this purpose, optimization process was incorporated into comprehensive finite ...
