How can I optimize backtracking algorithms?
To optimize backtracking, you can use techniques like pruning, memoization, and constraint propagation.
What is pruning in backtracking?
Pruning involves eliminating paths that won't lead to a solution, reducing the search space.
Can you give an example of pruning in a backtracking algorithm?
Sure! In the N-Queens problem, if you place a queen in a row, you can prune columns and diagonals where other queens can't be placed.
What are some common problems that use backtracking?
Common problems include the N-Queens problem, Sudoku solving, and the Hamiltonian path problem.
