What Is a Fast Infoset?
In game theory, the information set refers to the set of actions that can occur in all games based on the observations for a particular participant. If the game is perfectly informative, each information set can have only one participant, and it shows the stage the game is in. Otherwise, some participants may not know the status of the game and the situation around them. [1]
- Specifically, in the extended form of the game, the information set is a series of decision nodes, such as:
1. Each node describes only one participant.
- 2. Participants cannot distinguish between multiple nodes in the information set. That is to say: if the information set has multiple nodes, the participants to which the information set belongs do not know which node they can move to.

- XML Information Set ( XML Information Set , abbreviation XML Infoset ) is a W3C specification (specification), which uses an information item to describe an abstract data model of an XML document. The XML Information Set is intended to be used in other specifications to reference information in well-formed XML documents. [2]
- An XML document has an information set as long as it is well-formed and meets the constraints of the XML namespace. The existence of an XML document information set does not require the XML document to be valid.
- The information set can contain a total of 11 different types of information items.
- Document Information Item (always exists)
- Element Information Item
- Attribute Information Item
- PI Information Item (Processing Information Information Item)
- Unexpanded Entity Reference Information Item
- Character Information Item
- Comment Information Item
- The Document Type Declaration Information Item
- Unparsed Entity Information Item
- Format Information Item
- Namespace Information Item
