Center node: "monotonicity constraints for termination in the integer domain"
  Abstract: Size-Change Termination (SCT) is a method of proving program termination#N#based on the impossibility of infinite descent. To this end we use a program#N#abstraction in which transitions are described by Monotonicity Constraints over#N#(abstract) variables. When only constraints of the form x>y' and x\geq y' are#N#allowed, we have size-change graphs. In the last decade, both theory and#N#practice have evolved significantly in this restricted framework. The crucial#N#underlying assumption of most of the past work is that the domain of the#N#variables is well-founded. In a recent paper I showed how to extend and adapt#N#some theory from the domain of size-change graphs to general monotonicity#N#constraints, thus complementing previous work, but remaining in the realm of#N#well-founded domains. However, monotonicity constraints are, interestingly,#N#capable of proving termination also in the integer domain, which is not#N#well-founded. The purpose of this paper is to explore the application of#N#monotonicity constraints in this domain. We lay the necessary theoretical#N#foundation, and present precise decision procedures for termination; finally,#N#we provide a procedure to construct explicit global ranking functions from#N#monotonicity constraints in singly-exponential time, and of optimal worst-case#N#size and dimension (ordinal).
