At least one publisher [3] includes the constraint that a given combination of numbers can only be used once in each grid, but still markets the puzzles as plain Kakuro. Some publishers prefer to print their Kakuro grids exactly like crossword grids, with no labeling in the black cells and instead numbering the entries, providing a separate ...
A crossword creator might choose to clue the answer SEN (as in the abbreviation for "senator") as "Washington bigwig: Abbr." or "Member of Cong.", with the abbreviation in the clue indicating that the answer is to be similarly abbreviated. [7] The use of "Var." indicates the answer is a variant spelling (e.g., EMEER instead of EMIR), while the ...
Example grid for a cross-figure puzzle with some answers filled in. A cross-figure (also variously called cross number puzzle or figure logic) is a puzzle similar to a crossword in structure, but with entries that consist of numbers rather than words, where individual digits are entered in the blank cells.
By early 1997, Parker’s puzzle became the "Universal Crossword" syndicated by Universal Press Syndicate to newspapers and clients worldwide. In 1999, together with Universal Press Syndicate’s Uclick division, Parker founded The Puzzle Society, and is the founder and senior editor of the Universal Uclick line of crossword puzzles and games.
Shifting the burden to the intervenor. A special case of the “Shifting the Burden” systems archetype that occurs when an intervenor is brought in to help solve an ongoing problem. Over time, as the intervenor successfully handles the problem, the people within the system become less capable of solving the problem themselves.
The project management triangle (called also the triple constraint, iron triangle and project triangle) is a model of the constraints of project management. While its origins are unclear, it has been used since at least the 1950s. [1] It contends that: The quality of work is constrained by the project's budget, deadlines and scope (features).
Constraint satisfaction problems (CSPs) are mathematical questions defined as a set of objects whose state must satisfy a number of constraints or limitations. CSPs represent the entities in a problem as a homogeneous collection of finite constraints over variables , which is solved by constraint satisfaction methods.
Alternatively, if the constraints are all equality constraints and are all linear, they can be solved for some of the variables in terms of the others, and the former can be substituted out of the objective function, leaving an unconstrained problem in a smaller number of variables.
