A web-based user interface enables physicians to carry out a full diagnosis process on a simulated patient, given as a pre-defined clinical vignette. By collecting the physician’s information queries and hypothesis revisions, highly detailed diagnostic reasoning trajectories are captured leading to a diagnosis and its justification. Four expert epileptologists with a mean experience of 19 years were recruited to evaluate the system and share their impressions in semi-structured interviews. We find that the recorded trajectories validate proposed theories on broader diagnostic reasoning, while also providing valuable additional details extending previous findings.","lang":"eng"}],"status":"public","file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":486513,"file_id":"55430","access_level":"closed","file_name":"Battefeld_2024_Revealing-the-dynamics.pdf","date_updated":"2024-07-30T08:21:13Z","date_created":"2024-07-30T08:21:13Z","creator":"doba2"}],"publication":"Proceedings of the 46th Annual Conference of the Cognitive Science Society","type":"conference","keyword":["Differential Diagnosis","Diagnostic Reasoning","Reasoning Process Analysis","Seizure","Epilepsy"],"ddc":["000"],"language":[{"iso":"eng"}],"file_date_updated":"2024-07-30T08:21:13Z","_id":"55429","project":[{"name":"TRR 318 - C5: TRR 318 - Subproject C5","_id":"128"}],"department":[{"_id":"660"}],"user_id":"91864"},{"publication_identifier":{"isbn":["9798400702020"]},"page":"129–139","citation":{"apa":"Prager, R.

However, these benchmark functions have faced criticism for their limited resemblance to real-world problems. In response, recent research has focused on automatically generating new benchmark functions for areas where established test suites are inadequate. These approaches have limitations, such as the difficulty of generating new benchmark functions that exhibit exploratory landscape analysis (ELA) features beyond those of existing benchmarks.The objective of this work is to develop a method for generating benchmark functions for single-objective continuous optimization with user-specified structural properties. Specifically, we aim to demonstrate a proof of concept for a method that uses an ELA feature vector to specify these properties in advance. To achieve this, we begin by generating a random sample of decision space variables and objective values. We then adjust the objective values using CMA-ES until the corresponding features of our new problem match the predefined ELA features within a specified threshold. By iteratively transforming the landscape in this way, we ensure that the resulting function exhibits the desired properties. To create the final function, we use the resulting point cloud as training data for a simple neural network that produces a function exhibiting the target ELA features. We demonstrate the effectiveness of this approach by replicating the existing functions of the well-known BBOB suite and creating new functions with ELA feature values that are not present in BBOB."}],"department":[{"_id":"34"},{"_id":"819"}],"series_title":"FOGA ’23","user_id":"15504","_id":"47522","language":[{"iso":"eng"}],"keyword":["Benchmarking","Instance Generator","Black-Box Continuous Optimization","Exploratory Landscape Analysis","Neural Networks"]},{"year":"2023","place":"New York, NY, USA","page":"1546–1554","citation":{"apa":"Bossek, J., & Sudholt, D.

Here k is a granularity parameter 1 {$\\leq$} k {$\\leq$} n+1.

On combinatorial problems we show that QD finds a (1 - 1/e)-approximation when maximising any monotone sub-modular function with a single uniform cardinality constraint efficiently. Defining the feature space as the number of connected components of a connected graph, we show that QD finds a minimum spanning tree in expected polynomial time.","lang":"eng"}],"status":"public","publication":"Proceedings of the Genetic and Evolutionary Computation Conference","type":"conference","keyword":["quality diversity","runtime analysis"],"extern":"1","language":[{"iso":"eng"}],"_id":"48872","department":[{"_id":"819"}],"user_id":"102979","series_title":"GECCO’23"},{"publication":"Proceedings of the Genetic} and Evolutionary Computation Conference","abstract":[{"lang":"eng","text":"Generating new instances via evolutionary methods is commonly used to create new benchmarking data-sets, with a focus on attempting to cover an instance-space as completely as possible.

We address this issue by training a model based on Principal Component Analysis on existing instances to create a low-dimension projection of the high-dimension feature-vectors, and then apply Novelty Search directly in the new low-dimension space. We conduct experiments to evolve diverse and discriminatory instances of Knapsack Problems, comparing the use of Novelty Search in the original feature-space to using Novelty Search in a low-dimensional projection, and repeat over a given set of dimensions. We find that the methods are complementary: if treated as an ensemble, they collectively provide increased coverage of the space.

We ask a fundamental question: if additional search points are declared optimal, or declared as desirable target points, do these additional optima speed up evolutionary algorithms? More formally, we analyse the expected hitting time of a target set OPT{$\\cup$}S where S is a set of non-optimal search points and OPT is the set of optima and compare it to the expected hitting time of OPT. We show that the answer to our question depends on the number and placement of search points in S. For all black-box algorithms and all fitness functions with polynomial expected optimisation times we show that, if additional optima are placed randomly, even an exponential number of optima has a negligible effect on the expected optimisation time. Considering Hamming balls around all global optima gives an easier target for some algorithms and functions and can shift the phase transition with respect to offspring population sizes in the (1,{$\\lambda$}) EA on OneMax. However, for the one-dimensional Ising model the time to reach Hamming balls of radius (1/2-{$ϵ$})n around optima does not reduce the asymptotic expected optimisation time in the worst case. Finally, on functions where search trajectories typically join in a single search point, turning one search point into an optimum drastically reduces the expected optimisation time.","lang":"eng"}],"status":"public","date_updated":"2023-12-13T10:51:07Z","date_created":"2023-11-14T15:58:56Z","author":[{"first_name":"Jakob","full_name":"Bossek, Jakob","id":"102979","orcid":"0000-0002-4121-4668","last_name":"Bossek"},{"first_name":"Dirk","full_name":"Sudholt, Dirk","last_name":"Sudholt"}],"title":"Do Additional Target Points Speed Up Evolutionary Algorithms?","doi":"10.1016/j.tcs.2023.113757","publication_identifier":{"issn":["0304-3975"]},"year":"2023","page":"113757","citation":{"chicago":"Bossek, Jakob, and Dirk Sudholt. “Do Additional Target Points Speed Up Evolutionary Algorithms?” Theoretical Computer Science, 2023, 113757. https://doi.org/10.1016/j.tcs.2023.113757.","ieee":"J.

Research emphasizes technical challenges of such tools but also mentions severe usability shortcomings. These shortcomings hinder the adoption of static analysis tools, and user dissatisfaction may even lead to tool abandonment. To comprehensively assess the state of the art, we present the first systematic usability evaluation of a wide range of static analysis tools. We derived a set of 36 relevant criteria from the literature and used them to evaluate a total of 46 static analysis tools complying with our inclusion and exclusion criteria - a representative set of mainly non-proprietary tools. The evaluation against the usability criteria in a multiple-raters approach shows that two thirds of the considered tools off er poor warning messages, while about three-quarters provide hardly any fix support. Furthermore, the integration of user knowledge is strongly neglected, which could be used for instance, to improve handling of false positives. Finally, issues regarding workflow integration and specialized user interfaces are revealed. These findings should prove useful in guiding and focusing further research and development in user experience for static code analyses."}],"status":"public","_id":"52662","user_id":"32312","department":[{"_id":"76"}],"keyword":["Automated static analysis","Software usability"],"language":[{"iso":"eng"}]},{"publication_identifier":{"isbn":["978-3-88579-726-5"]},"place":"Bonn","year":"2023","page":"105–106","citation":{"ama":"Schlichtig M, Sassalla S, Narasimhan K, Bodden E.

Unfortunately, APIs can be misused, which can have catastrophic consequences, especially if the APIs provide security-critical functionalities like cryptography. Understanding what API misuses are, and how they are caused, is important to prevent them, eg, with API misuse detectors. However, definitions for API misuses and related terms in literature vary. This paper presents a systematic literature review to clarify these terms and introduces FUM, a novel Framework for API Usage constraint and Misuse classification. The literature review revealed that API misuses are violations of API usage constraints. To address this, we provide unified definitions and use them to derive FUM. To assess the extent to which FUM aids in determining and guiding the improvement of an API misuses detector’s capabilities, we performed a case study on the state-of the-art misuse detection tool CogniCrypt. The study showed that FUM can be used to properly assess CogniCrypt’s capabilities, identify weaknesses and assist in deriving mitigations and improvements."}],"status":"public","_id":"52660","department":[{"_id":"76"}],"user_id":"32312","keyword":["API misuses API usage constraints","classification framework","API misuse detection","static analysis"],"language":[{"iso":"eng"}]},{"doi":"10.4171/aihpc/73","title":"A quantitative strong parabolic maximum principle and application to a taxis-type migration–consumption model involving signal-dependent degenerate diffusion","date_created":"2024-04-07T12:34:35Z","author":[{"last_name":"Winkler","full_name":"Winkler, Michael","first_name":"Michael"}],"publisher":"European Mathematical Society - EMS - Publishing House GmbH","date_updated":"2024-04-07T12:36:00Z","citation":{"short":"M.

They both include the Poisson semigroup. We show that on a complete, connected, and non-compact Riemannian manifold of non-negative Ricci curvature, in both cases, the solution with $$L^1$$\r\n \r\n L\r\n 1\r\n \r\n initial data behaves asymptotically as the mass times the fundamental solution. Similar long-time convergence results remain valid on more general manifolds satisfying the Li-Yau two-sided estimate of the heat kernel. The situation changes drastically on hyperbolic space, and more generally on rank one non-compact symmetric spaces: we show that for the Poisson semigroup, the convergence to the Poisson kernel fails -but remains true under the additional assumption of radial initial data.","lang":"eng"}],"author":[{"full_name":"Papageorgiou, Efthymia","id":"100325","last_name":"Papageorgiou","first_name":"Efthymia"}],"date_created":"2024-04-17T13:17:37Z","publisher":"Springer Science and Business Media LLC","date_updated":"2024-04-17T13:19:59Z","doi":"10.1007/s11118-023-10109-1","title":"Large-Time Behavior of Two Families of Operators Related to the Fractional Laplacian on Certain Riemannian Manifolds","publication_identifier":{"issn":["0926-2601","1572-929X"]},"publication_status":"published","citation":{"apa":"Papageorgiou, E.

In this paper, an approach for a future traffic control system for mixed autonomy traffic environments is presented. Furthermore, a simulation framework based on the city of Paderborn is introduced to enable the development and examination of such a system. This encompasses multiple elements including the road network itself, traffic lights, sensors as well as methods to analyse the topology of the network. Furthermore, a procedure for traffic demand generation and routing is presented based on statistical data of the city and traffic data obtained by measurements. The resulting model can receive and apply the generated control inputs and in turn generates simulated sensor data for the control system based on the current system state.","lang":"eng"}]},{"external_id":{"arxiv":["2112.12619"]},"language":[{"iso":"eng"}],"ddc":["510"],"keyword":["Lagrangian learning","variational backward error analysis","modified Lagrangian","variational integrators","physics informed learning"],"publication":"Journal of Computational and Applied Mathematics","file":[{"relation":"main_file","file_id":"32274","access_level":"open_access","description":"The principle of least action is one of the most fundamental physical principle.
