A logical spreadsheet is a spreadsheet in which formulas take the form of logical constraints rather than function definitions.. In traditional spreadsheet systems, such as Excel, cells are partitioned into "directly specified" cells and "computed" cells and the formulas used to specify the values of computed cells are "functional", i.e. for every combination of values of the directly ...
In mathematics and logic, the term "uniqueness" refers to the property of being the one and only object satisfying a certain condition. [1] This sort of quantification is known as uniqueness quantification or unique existential quantification, and is often denoted with the symbols "∃!"
Open Formula resulted from the belief by some users that the syntax and semantics of table formulas were not defined in sufficient detail. Version 1.0 of the specification defined spreadsheet formulae using a set of simple examples which show, for example, how to specify ranges and the SUM() function.
Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within. A cell containing a formula, therefore, has two display components ...
UNIQUE SAT [22] is the problem of determining whether a formula has exactly one assignment. It is complete for US , [ 23 ] the complexity class describing problems solvable by a non-deterministic polynomial time Turing machine that accepts when there is exactly one nondeterministic accepting path and rejects otherwise.
Victims identified as artistic student and caring teacher. The tragic deaths of a teen student and substitute teacher at Abundant Life Christian School shook the tightly connected school community.
WASHINGTON (Reuters) -The FBI has been investigating a longtime Exxon Mobil consultant over the contractor's alleged role in a hack-and-leak operation that targeted hundreds of the oil company’s ...
