brute force, the application of predominantly physical
effort to achieve a goal that could be accomplished with
less effort if more carefully considered. figuratively,
repetitive or strenuous application of an obvious or
simple tactic, as contrasted with a more clever stratagem
achieving the same goal with less effort; -- as, the first
prime numbers were discovered by the brute force
repetition of the sieve of eratosthenes.

brute force adj. describes a primitive programming style, one in which
the programmer relies on the computer's processing power instead of
using his or her own intelligence to simplify the problem, often
ignoring problems of scale and applying naive methods suited to small
problems directly to large ones. the term can also be used in reference
to programming style: brute-force programs are written in a heavyhanded,
tedious way, full of repetition and devoid of any elegance or useful
abstraction see also brute force and ignorance.
the canonical example of a brute-force algorithm is associated with
the `traveling salesman problem' tsp, a classical np-hard problem:
suppose a person is in, say, boston, and wishes to drive to n other
cities. in what order should the cities be visited in order to minimize
the distance travelled? the brute-force method is to simply generate all
possible routes and compare the distances; while guaranteed to work and
simple to implement, this algorithm is clearly very stupid in that it
considers even obviously absurd routes like going from boston to
houston via san francisco and new york, in that order. for very small n
it works well, but it rapidly becomes absurdly inefficient when n
increases for n = 15, there are already 1,307,674,368,000 possible
routes to consider, and for n = 1000 -- well, see bignum. sometimes,
unfortunately, there is no better general solution than brute force. see
also np-.
a more simple-minded example of brute-force programming is finding the
smallest number in a large list by first using an existing program to
sort the list in ascending order, and then picking the first number off
the front.
whether brute-force programming should actually be considered stupid
or not depends on the context; if the problem is not terribly big, the
extra cpu time spent on a brute-force solution may cost less than the
programmer time it would take to develop a more `intelligent' algorithm.
additionally, a more intelligent algorithm may imply more long-term
complexity cost and bug-chasing than are justified by the speed
improvement.
ken thompson, co-inventor of unix, is reported to have uttered the
epigram "when in doubt, use brute force". he probably intended this as a
ha ha only serious, but the original unix kernel's preference for
simple, robust, and portable algorithms over brittle `smart' ones does
seem to have been a significant factor in the success of that os. like
so many other tradeoffs in software design, the choice between brute
force and complex, finely-tuned cleverness is often a difficult one that
requires both engineering savvy and delicate esthetic judgment.
