	abstract = {The iteration history curve of optimization algorithms is a saturation- type development curve or sigmoid shape curve. After an overview of several different sigmoid curves, the iteration history curve of the RVA (Random Virus Algorithm) is analysed in order to find its best settings for a given optimization problem. The analysis of the characteristics and numerical parameters of the iteration history curve provides the possibility to discover the speed and efficiency of the algorithm without the necessity to wait throughout the whole running until its final result, which can speed up numerical experiments during the search for the solution to the optimization problem and while ‘fine tuning’ the algorithm to the given task. Since sigmoid-type curves can be found in many different fields of life (the history of the sport world records, comparison of the achievements of several groups), the results of this analysis can be used in several different domains of life, when the ranking, comparison, evaluation or qualification of several individuals or groups is important.},

The aim of this study is to improve the performance of a lathe spindle system in terms of chatter occurrence, while maintaining the same overall mass of the system. The design of the spindle system is optimized using the grapho-optimization method, employing the Kuhn-Tucker optimality criterion to evaluate the design parameters. Specifically, the thickness of the spindle shaft and the diameter of the shaft next to the chuck are varied. The optimized spindle system shows a significant improvement in the first natural frequency value compared to the original design; the first natural frequency is increased by 59.7 %.},

The same program is written in the two different programming language and the resulting program listings is compared. The demonstration optimization problem is to find the minimum safe radius of an L-shape model, loaded by a uniform surface pressure. The program to solve this optimization task builds the model, solves the finite element problem, and iteratively improves the radius until the optimum solution. In both cases, when the program running ends, we will see the optimum structure on the screen, and we can use the menu possibilities of the finite element system to see any details of the optimized model or listing the values of the parameters.},

A lot of research has been carried out in this domain to understand this phenomenon, which leads to finding ways to detect, identify, avoid, reduce, and control chatter in turning processes. In this paper, chatter research related to turning processes is reviewed and summarized. The main goal of this review paper is to compare different chatter prediction, suppression, and avoidance techniques to find out the most effective technique, so a scope of a work related to turning processes chatter is defined.},
