DisLog - Graphical User Interface
This graphical user interface allows to apply a DisLog operator
to a disjunctive logic program.
You can choose a type of Semantics.
Then you will get a form where you can select a special operator,
enter a program, and apply the operator to it.
Semantics of Disjunctive Logic Programs
DisLog provides the following approaches for evaluating logic
Syntax of Disjunctive Logic Programs
A disjunctive logic program is a collection of Prolog-style
rules of the form
where `;' denotes disjunction, `,' denotes conjunction,
and `~' denotes default negation.
The rules must be range-restricted, which means that all variable
symbols occuring in a rule must occur in at least one of the positive body
