Complexity Analysis of Backtracking
Since backtracking algorithm is purely brute force therefore in terms of time complexity, it performs very poorly. Generally backtracking can be seen having below mentioned time complexities:
- Exponential (O(K^N))
- Factorial (O(N!))
These complexities are due to the fact that at each state we have multiple choices due to which the number of paths increases and sub-trees expand rapidly.
Introduction to Backtracking – Data Structure and Algorithm Tutorials
Backtracking is like trying different paths, and when you hit a dead end, you backtrack to the last choice and try a different route. In this article, we’ll explore the basics of backtracking, how it works, and how it can help solve all sorts of challenging problems. It’s like a method for finding the right way through a complex choices.
