Automated program repair (APR) is a challenging process of detecting bugs, localizing
buggy code, generating fix candidates and validating the fixes. Effectiveness of program …

In this work, we present a semi-decision procedure for a fragment of separation logic with
user-defined predicates and Presburger arithmetic. To check the satisfiability of a formula …

We consider the satisfiability problem for a fragment of separation logic including inductive
predicates with shape and arithmetic properties. We show that the fragment is decidable if …

Automatic Program Repair (APR) has recently been an emerging research area, addressing
an important challenge in software engi-neering. APR techniques, if effective and efficient …

Heap-manipulating programs are known to be challenging to reason about. We present a
novel verifier for heap-manipulating programs called S2TD, which encodes programs …

In separation logic, bi-abduction-a combination of abductive inference and frame inference-
is the key enabler for compositional reasoning, helping to scale up verification significantly …

Symbolic execution is an important and popular technique used in several software
engineering tools for test case generation, debugging and program analysis. As such …

The process of completing, correcting and prioritising specifications is an essential but very
complex task for the maintenance and improvement of software systems. The preservation of …

Shape analysis is of great importance for the verification of the correctness and memory-
safety of heap-manipulating programs, yet such analyses have been shown to be highly …

On NVIDIA's many-core GPUs, there is no synchronization function among parallel thread
blocks. When fine-granularity of data communication and synchronization is required for …
