Modern applications often manage time-varying data. Despite decades of research on temporal databases, which culminated in the addition of temporal data operations into the SQL:2011 standard, temporal data query and manipulation operations are unavailable in most mainstream datab…
Coping with different and changing requirements leads to concurrent products (variability in space) and subsequent revisions (variability in time). Moreover, products consist of interrelated models that represent different kinds of artifacts. Dependencies and redundancies between…
Racket provides for loops with macro-extensible sequence expressions. Sequence macros offer better performance than dynamic sequence implementations, but they are complicated to define and Racket offers little support for creating new sequence macros by combining existing ones. I…
Internet of Things (IoT) devices and the software they execute are often strongly coupled with vendors preinstalling their software at the factory. Future IoT applications are expected to be distributed via app stores. A strong coupling between hard- and software hinders the rise…
Unmanned Aerial Systems (UAS, typically known as drones) are useful in many application domains, such as logistics and precision farming, especially when they fly Beyond Visual Line of Sight (BVLOS). To effectively use multiple UAS for BVLOS missions, it is required to precisely …
Genetic Programming (GP) is an heuristic method that can be applied to many Machine Learning, Optimization and Engineering problems. In particular, it has been widely used in Software Engineering for Test-case generation, Program Synthesis and Improvement of Software (GI). Gramm…
Generic programming is a powerful paradigm abstracting data structures and algorithms to improve their reusability, as long as they respect a given interface. Coupled with a performance-driven language, it is a paradigm of choice for scientific libraries where the implementation …
Even code that is free of smells may be at high risk of forming them. In such cases, developers can either perform preventive refactoring in order to reduce this risk, or leave the code as is and perform corrective refactoring as smells emerge. In practice, however, developers us…
Validating a configurable software system is challenging, as there are potentially millions of configurations, which makes testing each configuration individually infeasible. Thus, existing sampling algorithms allow to compute a representative subset of configurations, called sam…
The operational behavior of control operators has been studied comprehensively in the past few decades, but type systems of control operators have not. There are distinct type systems for shift, control, and shift0 without any relationship between them, and there has not been a t…
Turn-based games such as chess are very popular, but tool-chains tailored for their development process are still rare. In this paper we present a model-driven and generative toolchain aiming to cover the whole development process of rule-based games. In particular, we present a …
Incremental computations react to input changes by updating their outputs. Compared to a non-incremental rerun, incremental computations can provide order-of-magnitude speedups, since often small input changes trigger small output changes. One popular means for implementing incre…
The dream of developing compilers that automatically verify whether or not programs meet their specifications remains an ongoing challenge. Such "verifying compilers" are (finally) on the verge of entering mainstream software development. This is partly due to advancements made o…
C++ is a multi-paradigm language that enables the programmer to set up efficient image processing algorithms easily. This language strength comes from many aspects. C++ is high-level, so this enables developing powerful abstractions and mixing different programming styles to ease…
The Java Stream API was introduced in Java 8, allowing developers to express computations in a functional style by defining a pipeline of data-processing operations. Despite the growing importance of this API, there is a lack of benchmarks specifically targeting stream-based appl…
One of the performance bottlenecks of nested recursive computations is the intermediate collections created at different levels of recursion. The existing techniques such as vertical and horizontal loop fusion do not remove such intermediate allocations. This paper proposes deep …
Many problems require working with data that varies in its structure and content. Current approaches, such as schema evolution or data integration tools, are highly tailored to specific kinds of variation in databases. While these approaches work well in their roles, they do not …
Machine learning is a discipline which has become ubiquitous in the last few years. While the research of machine learning algorithms is very active and continues to reveal astonishing possibilities on a regular basis, the wide usage of these algorithms is shifting the research f…
Cryptographic techniques have the potential to enable distrusting parties to collaborate in fundamentally new ways, but their practical implementation poses numerous challenges. An important class of such cryptographic techniques is known as Secure Multi-Party Computation (MPC). …
Low-code application platforms enable citizen developers to autonomously build complete applications, such as web applications or mobile applications. Some of these platforms also offer support for reuse to facilitate the development of similar applications. The offered mechanism…
