Unconstrained numerical optimization using real-coded genetic algorithms: a study case using benchmark functions in R from Scratch

A comparative study of some real-coded genetic algorithms for unconstrained global optimization

In this paper, a set of new Real-Coded Genetic Algorithms (RCGAs) with local and global exploratory search capabilities are proposed. The search capabilities are based on the inclusion of a modified crossover procedure and a new global exploratory method in RCGA. The global exploratory method is based on vector projection while the modified crossover procedure is based on a limited version of t...

Two Efficient Real-coded Genetic Algorithms for Real Parameter Optimization

This paper presents an efficient generation alternation model for real-coded genetic algorithm called rc-CGA. The most important characteristic of the proposed rcCGA model is the implicit self-adaptive feature in its crossover and mutation mechanism. By applying two crossover operators (BLX-α and UNDX crossover) in conjunction with Non-Uniform mutation to rc-CGA, respectively, we define two new...

Optimal Truss-Structure Design using Real-Coded Genetic Algorithms

Optimization of truss-structures for finding optimal cross-sectional size, topology, and configuration of 2-D and 3-D trusses to achieve minimum weight is carried out using real-coded genetic algorithms (GAs). All the above three optimization techniques have been made possible by using a novel representation scheme. Although the proposed GA uses a fixed-length vector of design variables represe...

Efficient Numerical Optimization Technique Based on Real-Coded Genetic Algorithm

Using Fuzzy Cognitive Maps for Prediction of Knowledge Worker Productivity Based on Real Coded Genetic Algorithm

  Improving knowledge worker productivity has been one of the most important tasks of the century. However, we have few measures or management interventions to make such improvement possible, and it is difficult to identify patterns that should be followed by knowledge workers because systems and processes in an organization are often regarded as a death blow to creativity. In this paper, we se...
