Puzzle

A puzzle is a game, problem, or toy that tests a person's ingenuity or knowledge. In a puzzle, one is required to put pieces together in a logical way, in order to arrive at the correct solution of the puzzle. There are different types of puzzles for different ages, such as crossword puzzles, word-search puzzles, number puzzles, or logic puzzles.

Puzzles are often devised as a form of entertainment but they can also arise from serious mathematical or logistical problems. In such cases, their solution may be a significant contribution to mathematical research.

Solutions of puzzles often require the recognition of patterns and the creation of a particular kind of order. Sometimes not because of how complicated and diagonal the pattern can get. People with a high level of inductive reasoning aptitude may be better at solving such puzzles than others. But puzzles based upon inquiry and discovery may be solved more easily by those with good deduction skills. Deductive reasoning improves with practice.

Puzzle (2010 film)

Puzzle (Spanish: Rompecabezas) is a 2010 Argentine drama film directed by Natalia Smirnoff. It was nominated for the Golden Bear at the 60th Berlin International Film Festival.

Plot

A middle-aged housewife, Maria del Carmen (Maria Onetto), suddenly finds she has a gift for assembling puzzles. Unbeknownst to her husband (Gabriel Goity) and two college-age sons, she begins practicing for a tournament with a man (Arturo Goetz) she met through an ad in a puzzle shop. The thrill "of a woman discovering her special gift and rejoicing in it" is just one of the surprises in store for Maria, as she starts to look differently at the pieces of her life, and to try new things.

Cast

Reception

Critical reception to the film was mostly positive, according to reviews cited at IMDb, with the notable exception of V.A. Musetto in the New York Post who said, "If the plot of the Argentine soaper Puzzle seems familiar, that's because it's nearly identical to the story in the French movie Queen To Play." Comparing this film to Lucrecia Martel's The Headless Woman, in which Maria Onetto starred in 2008, Stephen Holden of The New York Times said, "Although Puzzle is a much smaller, less ambitious film without the ominous political subtext of Ms. Martel's masterwork, its story...has implications about sexual inequality in Argentina's middle class." Holden also notes that Smirnoff served as Martel's casting director on the 2008 film. The A.V. Club says, "its conclusion is pleasing and not at all pat, a portrait of a woman who's learned she deserves to keep some things for herself."

American Video Entertainment

Combination

In mathematics, a combination is a way of selecting items from a collection, such that (unlike permutations) the order of selection does not matter. In smaller cases it is possible to count the number of combinations. For example, given three fruits, say an apple, an orange and a pear, there are three combinations of two that can be drawn from this set: an apple and a pear; an apple and an orange; or a pear and an orange. More formally, a k-combination of a set S is a subset of k distinct elements of S. If the set has n elements, the number of k-combinations is equal to the binomial coefficient

which can be written using factorials as whenever , and which is zero when . The set of all k-combinations of a set S is sometimes denoted by .

Combinations refer to the combination of n things taken k at a time without repetition. To refer to combinations in which repetition is allowed, the terms k-selection,k-multiset, or k-combination with repetition are often used. If, in the above example, it was possible to have two of any one kind of fruit there would be 3 more 2-selections: one with two apples, one with two oranges, and one with two pears.

Combination (chess)

In chess, a combination is a sequence of moves, often initiated by a sacrifice, which leaves the opponent few options and results in tangible gain. At most points in a chess game, each player has several reasonable options from which to choose, which makes it difficult to plan ahead except in strategic terms. Combinations, in contrast to the norm, are sufficiently forcing that one can calculate exactly how advantage will be achieved against any defense. Indeed, it is usually necessary to see several moves ahead in exact detail before launching a combination, or else the initial sacrifice would not be undertaken.

Definition

In 1952/53, the editors of Shakhmaty v SSSR decided on this definition: A combination is a forced sequence of moves which uses tactical means and exploits specific peculiarities of the position to achieve a certain goal. (Golombek 1977)

Irving Chernev said:

Example

A combination is usually built out of more fundamental chess tactics such as forks, pins, skewers, undermining, discovered attacks, etc. Thus a combination must be at least three moves long, but the longer it takes to recoup the initial sacrifice, the more impressive the combination. The position below from a game between G. Stepanov and Peter Romanovsky begins a combination which illustrates several forks and skewers.
