Pattern recognition (classification) algorithmic models and related structures were considered and
discussed since 70s: – one, which is formally related to the similarity treatment and so - to the discrete
isoperimetric property, and the second, - logic based and introduced in terms of Reduced Disjunctive Normal
Forms of Boolean Functions. A series of properties of structures appearing in Logical Models are listed and
interpreted. This brings new knowledge on formalisms and ontology when a logic based hypothesis is the model
base for Pattern Recognition (classification).
