Labels: Software Design agility Next, let's take a look at what is in the System Reconstruction toolbox, that is, to see what methods are available for system reconstruction. System refactoring always adjusts our code at different levels, so the refactoring method is divided into multiple layers. In general, the reconstruction methods are divided into the following layers: reconstruction of methods, objects, objects, inheritance systems, organization

Let's take a specific example of a genetic algorithm and find the minimum value of the rastrigin function. 1. rastrigin's Function In genetic algorithms, a function is often used to test the genetic algorithm. This function is the rastrigin function. The rastrigin function is defined as follows: The Genetic Algorithm Toolbox provides an M file, which is the implementation of this function. This file is rastriginsfcn. M. The following figure shows the
