OPTIMIZER is a user-friendly design optimization study tool that helps users to optimize almost any optimization problems. There are several optimization algorithms in OPTIMIZER program such as Genetic Algorithm (GA), Constraint Steepest Descent...

An algorithm for topological structural optimization using homogenization theory and optimality criteria methods is presented. Material models and homogenization theory are briefly introduced. Some examples of plane problems are presented, mainly...

This is the third part of a three paper review of homogenization and topology optimization. In the first two papers the homogenization theory and solution of the equations for different material models to be used in topology optimization...

A novel optimization algorithm, called the Magnetic Optimization Algorithms (MOAs), is proposed in this paper which is inspired by the principles of magnetic field theory. In MOA, the possible solutions are some magnetic particles scattered...

Shape optimization of 3-D structures is a challenging task. The newly developed isogeometrical analysis is a more suitable approach, in comparison with other numerical methods, to address the problem. Apart from the ability of defining...

Computational complexity is a prohibitive factor in evolutionary optimization of sufficiently large and/or complex problems. Much of this computational complexity is due to the fitness function evaluation that may either not exist...

Frequency optimization is an important issue in the design of structures subjected to dynamic loading. The response of a structure to dynamic loading depends mainly on the first natural frequency of the structure because the resonance occurs when...

The Isogeometric Analysis (IA) method is applied for structural topology optimization instead of the finite element method. For this purpose, the material density is considered as a continuous function throughout the design domain...
