AI Search Algorithms Interview Questions – Part 5
━━━━━━━━━━━━━━━━━━━━━━
01. What is a Constraint Satisfaction Problem (CSP)?
A Constraint Satisfaction Problem is an AI problem in which values are assigned to variables while satisfying a set of predefined constraints.
Key Points
- Variables and Domains
- Constraints between Variables
- Used in Sudoku and Timetable Scheduling
02. What is Backtracking Search?
Backtracking Search is an algorithm that builds a solution step by step. If a choice violates a constraint, it goes back and tries another option.
Key Points
- Explores possible solutions
- Rejects invalid choices
- Commonly used in CSPs
03. What is Arc Consistency in AI?
Arc Consistency is a technique used in Constraint Satisfaction Problems to remove domain values that cannot satisfy constraints between connected variables.
Key Points
- Reduces possible values
- Helps eliminate inconsistent choices
- Simplifies the search process
04. What is Forward Checking?
Forward Checking checks the domains of unassigned variables after a variable receives a value. It removes values that conflict with the current assignment.
Key Points
- Detects conflicts early
- Reduces unnecessary searching
- Commonly used with Backtracking Search
05. What is Constraint Propagation?
Constraint Propagation reduces the possible values of variables by repeatedly applying constraints until no further reduction is possible or a contradiction is found.
Key Points
- Reduces the search space
- Helps identify contradictions
- Used in Sudoku and scheduling problems
