In this chapter, we will give an overview over self-adaptive methods in evolutionary algorithms. Self-adaptation in its purest meaning is a state-of-the-art method to adjust the setting of control parameters. It is called self-adaptive because the algorithm controls the setting of these parameters itself – embedding them into an individual’s genome and evolving them. We will start with a short ...

We describe the application of a Perfectly Matched Layer (PML) combined with a self-adaptive goal-oriented hp Finite Element (FE) method to the simulation of resistivity measurements. The adaptive refinements and fast convergence of the self-adaptive hp FE method enhance the performance of the PML and, thus, enable the accurate and efficient truncation of the computational domain in open domain...

Learning Classifier System which replaces the genetic algorithm with the evolving cooperative population of discoverers is a focus of current research. This paper presents a modified version of XCS classifier system with self-adaptive discovery module. The new model was confirmed experimentally in a multiplexer environment. The results prove that XCS with the self-adaptive method for determinin...

Differential Evolution algorithm is a simple yet reliable and robust evolutionary algorithm for numeric optimization. However, fine-tuning control parameters of DE algorithm is a tedious and time-consuming task thus became a major challenge for its application. This paper introduces a novel self-adaptive method for tuning the amplification parameters F of DE dynamically. This method sampled app...

psychological findings show that a lower iq score than the normal level is notenough to recognize someone as mentally retarded. in addition they have visibleand specific difficulties in their adaptive behaviors. research on adaptivebehaviors is useful for those with specific needs and if mentally retarded childrenwant to adapt themselves to social life, they should improve their adaptivebehavio...

The auxiliary problem principle is a powerful tool for solving multi-area economic dispatch problem. One of the main drawbacks of the auxiliary problem principle method is that the convergence performance depends on the selection of penalty parameter. In this paper, we propose a self-adaptive strategy to adjust penalty parameter based on the iterative information, the proposed approach is verif...

This paper proposes a new self-adaptive genetic algorithm。This new algorithm divides the whole evolution process into three stages. At each stage, the new algorithm adopts different operation method. The main ideas are grading balance selection, continuous crossover operation. The new algorithm designs especially self-adaptive mutation probability according to the principle of searching for thi...

This paper provides a comparative study on the performances of standard PID and adaptive PID controllers tested on travel angle of a 3-Degree-of-Freedom (3-DOF) Quanser bench-top helicopter. Quanser, a well-known manufacturer of educational bench-top helicopter has developed Proportional Integration Derivative (PID) controller with Linear Quadratic Regulator (LQR) for all travel, pitch and yaw ...
