Termination of binary CLP programs has recently become an important question in the termination analysis community. The reason for this is due to the fact that some of the recent approaches to termination of logic programs abstract the input program to a binary CLP program and conclude termination of the input program from termination of the abstracted program. In this paper we introduce a class of binary CLP programs such that their termination can be proved by using linear level mappings. We show that membership to this class is decidable and present a decision procedure. Further, we extend this class to programs such that their termination proofs require a combination of linear functions. In particular we consider as level mappings tuples of linear functions and piecewise linear functions.
