Self notes: - Brute Force approach finds all the possible solutions and selects desired solution per given the constraints. - Dynamic Programming also uses Brute Force approach to find the OPTIMUM solution, either maximum or minimum. - Backtracking also uses Brute Force approach but to find ALL the solutions. - Solutions to the Backtracking problems can be represented as State-Space Tree. - The constrained applied to find the solution is called Bounding function. - Backtracking follows Depth-First Search method. - Branch and Bound is also a Brute Force approach, which uses Breadth-First Search method.

Other professors are using complicated examples that are available in reference books, but sir Abdul Bari has created his own simple and easy examples for every topic to teach students.. Thank u sir

You are the best who explained backtracking in just 8 minutes. I lost hours reading and watching and no one explain it easily like you. Thnaks
