  Force Fields - The Search for Undiscovered Force Fields
The existence of hereto undiscovered force fields, different from electric, magnetic, and gravitational fields could have a profound effect on the study of physics as well as medical, military, and communications uses.
In a "brute force" attempt to find undiscovered fields or related phenomena we could take samples of various materials and attempt to very precisely measure forces and energy.
Experiments in deep space may be useful in searching for unknown fields because the masking effect of very strong fields in Earth’s vicinity would be reduced.

  Brute-force search - Biocrawler   (Site not responding. Last check: )
In computer science, a brute-force search consists of systematically enumerating every possible solution of a problem until a solution is found, or all possible solutions have been exhausted.
searching the space of six-digit numbers takes only a million iterations: assuming a thousand instructions are needed to check the solution, a single modern computer can solve the problem in a billion instructions, or approximately a second at a rate of 1 billion instructions per second.
For example, in computer chess, rather than computing the full minimax tree of all possible moves for the remainder of the game, a more limited tree of minimax possibilities is computed, with the tree being pruned at a certain number of moves, and the remainder of the tree being approximated by a static evaluation function.

Proof by exhaustion, also known as the brute force method or case analysis, is a method of mathematical proof in which the statement to be proved is split into a finite number of cases, and each case is proved separately.
Category: Disambiguation Brute Force is a controversial book by historian John Ellis which proposes that the Allied Forces won World War II not by the skill of their leaders but by brute force.
Brute Force is the name of your squad of four: Tex the weapons expert, Hawk the stealth operative, Brutus the lizardman, and Flint the sniper.

 BRUTE-FORCE SEARCH : Encyclopedia Entry
In computer science, brute-force search or exhaustive search is a trivial but very general problem-solving technique, that consists of systematically enumerating all possible candidates for the solution and checking whether each candidate satisfies the problem's statement.
Therefore, brute-force search is typically used when the problem size is limited, or when there are problem-specific heuristics that can be used to reduce the set of candidate solutions to a manageable size.
For example, when searching for a proper divisor of a random number n, it is better to enumerate the candidate divisors in increasing order, from 2 to n - 1, than the other way around — because the probability that n is divisible by c is 1/c.

 A Brute Force Search of DES Keyspace
Brute force attacks like this are naturally suited to distributed or parallel computing efforts, since they essentially consist of a large number of independent problems--the testing of each key.
Although not a new attack by any means, brute force key search has been a metric by which the security of cryptosystems are judged.
While using this type of effort to do a brute force attack on a 64-bit key would be difficult today, it will certainly be possible in the not so distant future, as more people become involved in these efforts, and as CPU speeds increase according to Moore's Law.

 S/MIME Screen Saver
While the current state of computer hardware makes brute-force searches for 40-bit keys viable, not all searches are created equal.
The BRUTE (or BRUTESAV) program reads from a startup file, that tells it at what key to begin searching, and in which cycle that key is. (The cycles are numbered 0 to 27, from smallest to largest.) It then starts trial decryptions, saving its progress in the startup file every 2
If the first 40 bytes resulting from the decryption seems to be text, it is displayed, but the search continues.

 Life Search Programs
Description: Searches for slow-salvo constructions in Life (patterns that can be formed by starting from a blinker or block and colliding a single glider at a time into a previously constructed pattern, as described in Nicholas Gotts' paper "Self-Organized Construction in Sparse Random Arrays of Conway's Game of Life").
Backtracking search, pruning the search tree when the pattern exceeds given size bounds or when a self-overlapping sequence of components is detected (using an Aho-Corasick string matching automaton on a predefined list of impossible sequences).
At each level of search, tries all possible choices for the next column, and for each choice performs the evolution rule p times on the last 2p+1 columns (where p is the desired period).

Simply put, the brute force approach to backup no longer works.

Eliminating the search for changed data is at the heart of the "continuous data protection" (CDP) movement.

Minimax searches down to a certain depth, and treats the nodes at that depth as if they were terminal nodes, invoking a heuristic function (called a static evaluation function) to determine their values.
During search, when the maximizing player can show that the pessimistic value of an arc is greater than or equal to the optimistic values of any other arcs, it can either raise the lower bound on the most optimistic node, or lower the upper bound on all other nodes.
Search proceeds outward from islands in the search space; this form of search is usually from hierarchical planning.

 AI Qual Summary: Search Methods
In most search techniques that explore graphs, it is necessary to record two kinds of nodes: the nodes we have seen but not explored, and the nodes we have seen and explored.
Minimax searches down to a certain depth, and treats the nodes at that depth as if they were terminal nodes, invoking a heuristic function (called a static evaluation function) to determine their values.
During search, when the maximizing player can show that the pessimistic value of an arc is greater than or equal to the optimistic values of any other arcs, it can either raise the lower bound on the most optimistic node, or lower the upper bound on all other nodes.

 Frodo's Workshop - Boyer-Moore Algorithm   (Site not responding. Last check: )
Brute force is the simplest approach to string searching, but it's hardly the best.
Given a buffer M whose length is m and a search string N whose length is n, a brute force search through all of M for occurences of N requires at least m-n+1 individual comparisons.
Where a brute force comparison left-aligns the strings to be compared and begins with the first character in each string, Boyer-Moore left-aligns the strings and compares the last character of the search string to the corresponding character in the string to be searched.

Whereas one would expect to find a relative degree of depth and personality amongst the entire cast, the story does little to get the player involved or interested as to what Brute Force is all about.
On the whole, the ambience is practically non-existent and their behaviors are downright cowardly (most of the enemies simply hide behind rocks and duck in and out to hide and return fire).
