WebFor example, the Horn formula (1) can be rewritten (true !p 1) ^(p 2 ^p 3!false) ^(p 1 ^p 2!p 4): Horn clauses have numerous computer-science applications. In particular, the programming languages Prolog and Datalog are based on Horn clauses in rst-order logic. There is a simple polynomial-time algorithm to determine whether a given Horn formula F WebDescription. The Morisita and the Horn-Morisita indices measure the probability that individuals drawn one from each vector will belong to different species, relative to drawing from each vector separately. The Morisita index is formulated for count data only, whereas the Horn-Morisita index can be used with transformed counts or proportions.

A Horn formula is a propositional formula formed by conjunction of Horn clauses. The problem of Horn satisfiability is solvable in linear time. The problem of deciding the truth of quantified Horn formulas can be also solved in polynomial time.
