What is state?
A set of conditions or status of a system at a particular point in time
state explained in plain English
Analogy
Think of a state like a snapshot of a person's life at a specific moment. Just as a snapshot captures the person's current situation, a state captures the current situation of a system.
Example
A self-driving car's state might include its current speed, location, and surroundings, which are used to make decisions about steering, acceleration, and braking.
How is state used?
Common misconceptions about state
A common misconception is that a state is a fixed or static concept. However, in AI, states can change rapidly as new information becomes available or as the system interacts with its environment.
History
The concept of state has been used in AI since its early days, particularly in the development of finite state machines and Markov decision processes.
