Query: Why Can't You Behave? Non-termination Analysis of Direct Recursive Rules
  with Constraints   This paper is concerned with rule-based programs that go wrong. The unwanted
behavior of rule applications is non-termination or failure of a computation.
We propose a static program analysis of the non-termination problem for
recursion in the Constraint Handling Rules (CHR) language.
  CHR is an advanced concurrent declarative language involving constraint
reasoning. It has been closely related to many other rule-based approaches, so
the results are of a more general interest. In such languages, non-termination
is due to infinite applications of recursive rules. Failure is due to
accumulation of contradicting constraints during the computation.
  We give theorems with so-called misbehavior conditions for potential
non-termination and failure (as well as definite termination) of linear direct
recursive simplification rules. Logical relationships between the constraints
in a recursive rule play a crucial role in this kind of program analysis. We
think that our approach can be extended to other types of recursion and to a
more general class of rules. Therefore this paper can serve as a basic
reference and a starting point for further research.
