foetus -- Termination Checker for Simple Functional Programs (2407.06924v1)
Published 9 Jul 2024 in cs.PL and cs.LO
Abstract: We introduce a simple functional language foetus (lambda calculus with tuples, constructors and pattern matching) supplied with a termination checker. This checker tries to find a well-founded structural order on the parameters on the given function to prove termination. The components of the check algorithm are: function call extraction out of the program text, call graph completion and finding a lexical order for the function parameters.
