Center node: "structural resolution with co inductive loop detection"
  Abstract: Logic programming is the computer programming paradigm where a subset of first order logic, known as definite clause logic, is used as a general purpose programming language. A logic program is a finite set of sentences written in definite clause logic, defining relations among objects. A logic program interpreter, taking a program, answers queries about relations defined in the program, using some particular logical inference rule, such as SLD resolution, which is a special case of resolution rule restricted to definite clauses. Co-inductive SLD resolution (co-SLD) equips SLD resolution with loop detection to find in the logical deduction cyclic arguments such as A means B, while B means A, which used to cause non-termination of SLD resolution, and gives correct judgment about these arguments, making sure that the approved statements are all in a set called greatest complete Herbrand model, which specifies all possible logically true statements one can make from the given program. Structural resolution is an alternative inference rule for SLD resolution.A way to combine co-SLD style loop detection with structural resolution was found and is introduced in this paper, to extend structural resolution with co-induction. In particular, we present the operational semantics, called co-inductive structural resolution, of this novel combination and prove its soundness with respect to the greatest complete Herbrand model.
