Aggressive random testing tools (" fuzzers") are impressively effective at finding compiler
bugs. For example, a single test-case generator has resulted in more than 1,700 bugs …

Background: Program similarity is a fundamental concept, central to the solution of software
engineering tasks such as software plagiarism, clone identification, code refactoring and …

Open source software (OSS) allows developers to study, change, and improve the code free
of charge. There are several high-quality software projects which deliver stable and well …

Redundant source code hinders software maintenance, since updates have to be performed
in multiple places. This holds independent of whether redundancy was created by …

Smart contracts empowered by blockchains often manage digital assets in a distributed and
decentralized environment. People believe in smart contracts based on these new …

Ad-hoc reuse through copy-and-paste occurs frequently in practice affecting the evolvability
of software. This paper summarizes the state of the art in software clone management …

Background Research on empirical software engineering has increasingly been conducted
by analysing and measuring vast amounts of software systems. Hundreds, thousands and …

Code reuse through copying and pasting leads to so-called software clones. These clones
can be roughly categorized into identical fragments (type-1 clones), fragments with …

Measuring similarity between source codes has lots of applications, such as code plagiarism
detection, code clone detection, and malware detection. A variety of methods for the …

Text documents, including programs, typically have human-readable semantic structure.
Historically, programmatic access to these semantics has required explicit in-document …
