An Inference-Rule-Based Decision Procedure for Verification of Heap-Manipulating Programs with Mutab has blossomed recently, with many different approaches all showing leaps in performance and expressiveness. A year ago, we proposed a small logic for specifying predicates about HMPs and demonstrated that an inference-rule-based decision procedure could be performance-competitive, and in many cases

On Flat Programs with Listsly-linked list data structures. Since, in general, programs with lists are known to have the power of Turing machines, we restrict the control structure, by forbidding nested loops and destructive updates. Surprisingly, even with these simplifying conditions, verifying safety and termination for pro

Automata-Theoretic Model Checking RevisitedWe then use graph algorithms to search for a counterexample trace. The basic theory of this approach was worked out in the 1980s, and the basic algorithms were developed during the 1990s. Both explicit and symbolic implementations, such as SPIN and and SMV, are widely used. It turns out, however, th

These variants are defined via satisfaction parity games in which the Refuter can replace a concrete state with any state in the same partition before, respectively after, a quantifier move. These games are independent of the kind of abstraction. Our first variant makes the

Lattice Automatant, rather than a Boolean value. The automata-theoretic approach for reasoning about Boolean-valued systems has proven to be very useful and powerful. We develop an automata-theoretic framework for reasoning about multi-valued objects, and describe its application. The basis to our framework are . o

Maintaining Doubly-Linked List Invariants in Shape Analysis with Local Reasoning as doubly-linked lists. The algorithm abstracts and analyzes one single heap cell at a time. In order to maintain the structural invariants, the analysis uses a local heap abstraction that models the sub-heap consisting of one cell and its immediate neighbors. The proposed algorithm can successfull
