Game semantics

Game semantics is like playing a game where you and your friend have to take turns and make moves to win. In this game, the moves that we make represent the actions in a computer program.

Imagine you are playing a video game, for example, Super Mario Bros. In this game, Mario has to jump over obstacles to get to the end of the level. Now, let's say you and your friend want to make a program that behaves like Mario. Game semantics can help us to understand how to make that program work.

We can think of the program as a game, where there are two players - the program and the environment. The program has to make moves to get to the end, just like Mario. The environment also makes moves, which represent the obstacles that Mario has to jump over.

Game semantics helps us to understand how to make the program work by analyzing the different strategies that the players can use to win. We can represent these strategies using something called a game tree.

A game tree is like a family tree, where each node represents a move that a player can make. The branches of the tree represent the different options available to the player at each move. By analyzing the game tree, we can figure out the best strategies for the program and the environment to win the game.

So, in summary, game semantics is like playing a game to understand how to make a program work. It helps us to analyze the different strategies that players can use to win, represented by a game tree. By understanding these strategies, we can make our program better and more efficient.
