Search algorithms provide solutions for many problems, but they aren't always the optimal solution. Discover how constraint satisfaction algorithms are better than search algorithms in some cases, and how to use them.

WHAT YOU WILL LEARN

  • Define constraint satisfaction problems and describe how they are different from search problems
    List some examples of problems that are better for constraint satisfaction algorithms than search algorithms
    Describe how to use a backtracking search to solve a constraint satisfaction problem
    Describe how to order variables when performing a backtracking search
    Describe arc consistency and other types of constraint consistency in a constraint satisfaction problem
  • Describe how to use arc consistency to solve a constraint satisfaction problem with constraint propagation
    Describe how to use the backjumping and forward checking inference method in a backtracking search
    Describe how local search algorithms can be used to solve constraint satisfaction problems
    Describe how to represent a sudoku puzzle and how to solve it as a constraint satisfaction problem
    Build a full high-level representation and solution for a constraint satisfaction problem
