What is the definition of a complex system?

1. Descriptive definition of a complex system: A complex system is a system with a medium number of intelligent and adaptive subjects that take action based on local information.

2. The definition of complex system on Wikipedia: also known as a complex system, refers to a system composed of many components that may interact.

3. A complex system refers to a system composed of many components that may interact.Due to the dependence, relationship, or interaction between its components, or between a specific system and its environment, complex systems are inherently difficult to model. Complex systems mainly care about the behavior and characteristics of the system.

How to understand that human society is a complex system, and what systems is this system composed of, these...

1. The highest form of material movement, the organic system of various relationships formed by people's interaction and joint activities on the basis of the production of specific material materials. In Chinese, society refers to the place where the earth god was sacrificed in ancient times, which will be the gathering of people.

2. Therefore, human society is not an abstract singleThe mechanical addition of people is an organic system of interconnection and interaction formed by people in real activities and in real relationships. The organic unity of people and society is a basic point of view of grasping human society correctly in general.

3. The scope of ecosystems can be large or small, interlacing with each other. The largest ecosystem is the biosphere; the most complex ecosystem is the tropical rainforest ecosystem, and human beings mainly live in artificial ecosystems mainly in cities and farmland.

4. Practice is the origin and foundation of human society. Society originates from labor, and labor creates human society; labor not only creates and embodies the relationship between man and nature, but also constantly creates and embodies the social relationship between man and man, so practice is the activity mode and foundation of human society.

5. Inorganic environment is an abiotic component of an ecosystem, including sunlight and all other basic substances that make up the ecosystem, such as water, inorganic salts, air, organic matter, rocks, etc. Sunlight is a direct source of energy for most ecosystems. Water, air, inorganic salts and organic matter are indispensable material foundations for living things.

Three characteristics of complex systems

Complex systems are fundamentally different from the simple systems that have formed the focus of science since the Newtonian era. The interaction between simple systems is relatively weak, such as closed gases or distant galaxies, so that we can apply simple statistical average methods to study their behavior.

The basic characteristics of complex system definition. Due to the inconsistent definition of complex systems, there are at least more than 30 of them. Its representative features are as follows: (1) Complex systems are chaotic systems (chaotic schools). ( 2) Evolution system with adaptive ability (Santa Fe). ( 3) A hierarchical system containing multiple actors (Agents).

For complex systems, it will behave like a strong and elastic net. When you change any component, it will self-adjust to maintain a state of dynamic balance.

Systems usually have the characteristics of self-organization and have the ability to shape their own structure, generate new structures, learn, diversify and complicate. Even a very complex form of self-organization may arise from relatively simple organizational rules.

Definition of complex system

Definition 1: A complex system is a network composed of a large number of components. There is no central control, through Simple operating rules produce complex collective behaviors and complex information processing, and adaptability is generated through learning and evolution. Definition 2: A system with emergence and self-organizing behavior.

The definition of complex system on Wikipedia: also known as a complex system, refers to a system composed of many components that may interact.

A complex system is a difficult system to define. It exists in every corner of the world. In this way, we can also define it as follows: neither a simple system nor a random system.
