Chapter 5.4 Artificial Intelligence: Pathfinding
2. Introduction. Almost every game requires pathfindingAgents must be able to find their way around the game worldPathfinding is not a trivial problemThe fastest and most efficient pathfinding techniques tend to consume a great deal of resources . 3. Representing the Search Space. Agents need

Constraint Satisfaction Problems (Chapter 6)
Constraint Satisfaction Problems (Chapter 6). What is search for?. Assumptions: single agent, deterministic, fully observable, discrete environment Search for planning The path to the goal is the important thing Paths have various costs, depths Search for assignment

Review: Constraint Satisfaction Problems
Review: Constraint Satisfaction Problems. How is a CSP defined? How do we solve CSPs?. Backtracking search algorithm. Improving backtracking efficiency: Which variable should be assigned next? In what order should its values be tried? Can we detect inevitable failure early?.
