In computer science, backtracking is a method of solving Data structure and algorithm-based problems.  This technique solves the questions incrementally means, it solves a problem at a time. This technique is a kind of Brute force method of solving problems. 

The backtracking algorithm is applied to some specific sorts of problems. As an example, we will use it to seek out a feasible solution to a choice problem. It has also been found to be very effective for optimization problems.

For some cases, a backtracking algorithm is employed for the enumeration problem so as to seek out the set of all feasible solutions for the matter.

On the opposite hand, backtracking isn't considered an optimized technique to unravel a drag. It finds its application when the answer needed for drag isn't time-bounded.

Yes, the backtracking algorithm course by great learning is totally free of cost, and it covers all the basics of backtracking. This course on "Backtracking Algorithm" will cause you to understand how backtracking occurs and, therefore, the essential criteria for backtracking, post which you'll have an entire understanding of its algorithm with every constraint. Then finally, we'll implement the algorithm using Java and play with the input array. We'll also attempt to add some new constraints within the implementation and check out to vary the input. During this course, you'll first understand recursion, how it works internally, the three steps involved, what's meant by activation record, why one requires the bottom condition, etc. Then we mention one among the classic backtracking problems, i.e., Rat during a Maze. This backtracking algorithm is totally free so start learning today. 

This backtracking algorithms class is about 1 hr of video lectures, but you must devote some time to learning it. You must solve various problems based on a backtracking algorithm.

Yes, you will get a certificate of completion for Backtracking Algorithm after completing all the modules and cracking the assessment. The assessment tests your knowledge of the subject and badges your skills.
