The tool paper “The Probabilistic Termination Tool Amber” by Marcel Moosbrugger, Ezio Bartocci, Joost-Pieter Katoen and Laura Kovacs has been accpted to FM2021, the conference on Formal Methods. The paper presents the first tool that automates the checking whether a probabilistic program is AST, PAST, non-AST, non-PAST, or “don’t know”. (AST = almost-sure termination, PAST = positive AST).
