We guerlain ideal cologne introduce a logic for knowledge representation and reasoning on protein-protein interactions.Modulo a theory, formulas describe protein structures and dynamic changes.They can be composed in order to add or remove static and dynamic observations.A second-order circumscription operator then enables nonmonotonic reasoning on the changes implied by a formula.We introduce deduction rules that produce formulas which are, up to equivalence, in a first-order fragment with decidable royal nomadic 5413 rug satisfiability and validity.
Importantly, the rules can produce circumscribed formulas.
