Crossword Puzzles as a Constraint Problem
We present new results in crossword composition, showing that our program significantly outperforms previous successful techniques in the literature. We emphasize phase transition phenomena, and identify classes of hard problems. Phase transition is shown to occur when varying problem parameters, such as the dictionary size and the number of blocked cells on a grid, of large-size realistic prob...
متن کاملA Scrabble Crossword Game Playing Program
A program that plays the SCRABBLE Crossword Game has oeen designed and implemented in SIMULA 67 on a DECSystem-10 and in Pascal on a CYBER 173. The heart of the design is the data struc- t u r e for the lexicon and the algorithm for searching i t. The lexicon is represented as a l e t t e r table, or t r i e using a canonical ordering of the letter s in the words rather than the o r i g i n a...
متن کاملA probabilistic approach to solving crossword puzzles
We attacked the problem of solving crossword puzzles by computer: given a set of clues and a crossword grid, try to maximize the number of words correctly filled in. After an analysis of a large collection of puzzles, we decided to use an open architecture in which independent programs specialize in solving specific types of clues, drawing on ideas from information retrieval, database search, a...
متن کاملOn Vaughan Pratt's crossword problem
Vaughan Pratt has introduced objects consisting of pairs (A, W ) where A is a set and W a set of subsets of A, such that (i) W contains ∅ and A, (ii) if C is a subset of A×A such that for every a ∈ A, both {b | (a, b) ∈ C} and {b | (b, a) ∈ C} are members of W (a “crossword” with all “rows” and “columns” in W ), then {b | (b, b) ∈ C} (the “diagonal word”) also belongs to W, and (iii) for all di...
متن کاملCrossword Puzzle Attack on NLS
NLS is one of the stream ciphers submitted to the eSTREAM project. We present a distinguishing attack on NLS by Crossword Puzzle (CP) attack method which is newly introduced in this paper. We build the distinguisher by using linear approximations of both the non-linear feedback shift register (NFSR) and the nonlinear filter function (NLF). Since the bias of the distinguisher depends on the Kons...
