Its a algorithm. DPLL/Davis-Putnam-Logemann-Loveland algorithm is a complete, backtracking-based algorithm for deciding the satisfiability of propositional logic formulae in conjunctive normal form, i.e. for solving the CNF-SAT problem.

because it is more secure than any other algorithm.
The time complexity of the backtracking algorithm is typically exponential, O(2n), where n is the size of the problem.

Stack implementations allow us to easily implement backtracking algorithms.

The algorithm used in 8 queens problem is "Backtracking"Backtracking involves trial and error , where we try all the possibilities , if a trial leads to an error we eliminate it and also no two trials can be the same.Backtracking assumes that the problem is finite and is computable within the limitations of hardware.
The backtracking algorithm works by systematically trying out different options and backtracking when a dead end is reached. It efficiently explores all possible solutions in a search space by only considering viable choices at each step and discarding paths that are not promising. This process continues until a solution is found or all possibilities have been exhausted.

Backtracking is a general algorithmic technique that involves systematically trying all possible solutions to find the correct one, while depth-first search (DFS) is a specific graph traversal algorithm that explores as far as possible along each branch before backtracking. In essence, backtracking is a broader concept that can be used in various problem-solving scenarios, while DFS is a specific application of backtracking in graph traversal.
because it is more secure than any other algorithm.
Stacks are advantageous in enabling simple backtracking algorithms. That is the sole purpose of a stack, so there are no disadvantages as such.
