geatpy遗传算法包介绍（一）

Geatpy Overview

Geatpy is an open-source genetic algorithm package developed by several universities in China. It is a high-performance, practical evolutionary algorithm toolbox that offers library functions for important operations within various implemented evolutionary algorithms. With its highly modular and loosely coupled object-oriented evolutionary algorithm framework, Geatpy employs a "define problem class + call algorithm template" pattern for evolutionary optimization, suitable for solving single-objective optimization, multi-objective optimization, complex constraint optimization, combinatorial optimization, and mixed encoding evolutionary optimization.

Basic Problem Solving

The process of finding the optimal solution using the Geatpy package involves two main steps: the first step is constructing the problem framework, which includes writing the objective function and constraint functions; the second step is problem-solving. A brief example of solving a single-objective problem is presented.

Building the Problem Framework

The process of defining the problem starts with importing the necessary modules and writing the problem class, which includes the objective function, constraints, and other components. A code snippet of writing the problem framework is provided. It defines a maximization problem with the objective function f = x * np.sin(10 * np.pi * x) + 2.0 and a constraint -1 ≤ x ≤ 2.
