Creating Bruteforce Program Home. Programming Forum Software Development Forum. While this is probably a silly amount of effort for this sample program, you'll learn a surprising amount of real-world programming skills. From: Brute force may refer to any of several problem-solving methods involving the evaluation of multiple (or every) possible answer(s) for fitness. There are no standard 'brute force algorithms' because each problem is different. If you wanted to guess a password, brute force is literally generating every single possible password until you find the right one. If you wanted to guess a person's age, you could brute force by just starting from 1 and increasing by 1 every time, etc. – Nov 12 '11 at 6:53 •. ![]() It's brute force because you'd eventually reach the person's age, but you didn't do anything but try every possibility until one worked. An algorithm is not brute force if it exploits some advantage or approaches a problem such that you could arrive at a solution without having to try every possibility, ever. For example if a person was an adult, and you knew he was born in the 1970s, your 'guessing' algorithm would limit you to only 10 or so age possibilities, because you have some knowledge you can exploit to limit how many solutions you have to try. – Nov 12 '11 at 7:48 •. 1 and 3: Brute force means that you will go through all possible solutions extensively. For example, in a chess game, if you know you can win in two moves, the brute force will go through all possible combination of moves, without taking anything in consideration.

So the little pawn in the back that cannot influence the outcome will still be considered. 2: As you consider everything, the problem quickly goes out of control. Brute force through 15 moves in chess is impossible because of combinatorial explosion (too many situations to consider). However, more clever algorithms that take into account 'knowledge about the problem' can go much further (20-30 moves ahead) Edit: To clarify, brute force is simplest (dumbest?) way to explore the space of solutions. If you have a problem is set in a space (chess moves are countable, passwords are countable, continuous stuff is uncountable) brute force will explore this space considering all solutions equally. In the chess example, you want to checkmate your opponent. This is done via a sequence of moves, which is countable. Brute force will go through all sequence of moves, however unlikely they may be. The word unlikely is important, because it means that if you have knowledge about your problem (you know what is unlikely to be the solution, like sacrificing your queen), you can do much better than brute force.
