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
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.
Recursion is used for backtracking

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
I've never heard the term "finiteness" applied to an algorithm, but I think that's because the definition of an algorithm includes that it must be finite. So think of any algorithm and there is your example of finiteness.
An intractable problem is one for which there is an algorithm that produces a solution - but the algorithm does not produce results in a reasonable amount of time. Intractable problems have a large time complexity. The Travelling Salesman Problem is an example of an intractable problem.
