Currently, a paradigm shift is taking place from human interpretation of results towards machine interpretation. The long-term vision here is to automate the benchmarking process further to enable machines to automatically learn the properties of algorithms. This requires a more rigid benchmarking process with all assumptions and design decisions made explicit and accessible for machine interpretation.

In many real-world situations, the input to an algorithm is revealed piece-meal over time, and algorithmic decisions must be taken without knowledge of future inputs. This has given rise to the field of online algorithms. Traditionally, the performance of an online algorithm is measured by comparing the quality of the solution produced by the algorithm to that of an offline optimal solution. This framework, called competitive analysis, has led to a beautiful theory of worst-case analysis for online algorithms over the last few decades. At the same time, it has also been painfully obvious that this model is overly pessimistic in many situations and leads to strong lower bounds that bucket together algorithms with significant differences in observed empirical performance. In recent years, there has been an increasing push to go beyond worst-case competitive analysis of online algorithms, and several models and frameworks have been proposed that have attracted much research activity. This Dagstuhl Seminar seeks to bring together the leaders in online algorithms research to discuss and debate these approaches, helping chart the future of online algorithms for the foreseeable future.

Voronoi diagrams are fundamental geometric structures that divide space into regions based on proximity to points or sites. They play an important role in many fields of science and have become cornerstones of disciplines such as computational geometry, scientific computing, and optimization.

Key questions for the seminar include identifying which language constructs are best suited for expressing mixed precision algorithms in software and determining the specific floating-point formats required. This could provide valuable feedback to hardware developers. Additionally, the seminar should address which tools can aid in and simplify the analysis of reduced precision computing, and what tools might be necessary to evaluate the benefits of these techniques. For instance, how can algorithm developers predict and quantify the energy savings achieved through the use of reduced precision?

Faithful data representation is key. While this is universally true for visual analysis, the field of biological data communication has its unique challenges and open questions. Researchers need the right context to interpret data accurately, especially when uncertainties arise from factors like sampling choices or analysis parameters. Simplifying data for wider audiences must still convey its complexity and uncertainty to support informed decisions. This Dagstuhl Seminar will bring together experts in data visualisation and design, researchers, public educators, and journalists to explore methods for embracing and communicating biodata complexity and uncertainty.
