Backtracking algorithmn finds minimal path among the all.The main advantage of back tracking algorithmn as compare with greedy is to find minimal distance.In greedy ,it does.t know the optimal solution.It is used in Google earth.

4d + 7 = -15
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.
This is not a question, this is your homework. For a start, read this: https://en.wikipedia.org/wiki/Eight_queens_puzzle
because it is more secure than any other algorithm.

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.

I think it uses a special kind of algorithm called GENETIC ALGORITHM. Here is the link : http://en.wikipedia.org/wiki/Genetic_algorithm It uses backtracking: http://help.asctimetables.com/text.php?id=803&lang=en
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.

Recursion is used for backtracking
used in aircrats very fast it is not temparature sensitive
