Quantifiers metamorphoses. Generalizations, variations, algorithmic semantics
share
This article contains ideas and their elaboration for quantifiers, which appeared after checking in practice the experimental language of the formal knowledge representation YAFOLL [1]: - looking at for_all and exists quantifiers as operators clarifying two trivial properties of a function: the constancy of result value and presence of a value in the result; -It turned out that the quantifier term can be written in the lambda calculus technique, i.e. as definition; -quantifier of quantity # is introduced into the language, as needed in practice and does not cause logical and algorithmic problems on finite structures; - the quantifier of the sum is mentioned because it is a quantifier of the language; -algorithmic semantics is written for for_all and exists quantifiers as an introduction to the topic.
