  text: 'Classic automated algorithm selection (AS) for (combinatorial) optimization
    problems heavily relies on so-called instance features, i.e., numerical characteristics
    of the problem at hand ideally extracted with computationally low-demanding routines.
    For the traveling salesperson problem (TSP) a plethora of features have been suggested.
    Most of these features are, if at all, only normalized imprecisely raising the
    issue of feature values being strongly affected by the instance size. Such artifacts
    may have detrimental effects on algorithm selection models. We propose a normalization
    for two feature groups which stood out in multiple AS studies on the TSP: (a)
    features based on a minimum spanning tree (MST) and (b) nearest neighbor relationships
    of the input instance. To this end we theoretically derive minimum and maximum
    values for properties of MSTs and k-nearest neighbor graphs (NNG) of Euclidean
    graphs. We analyze the differences in feature space between normalized versions
    of these features and their unnormalized counterparts. Our empirical investigations
    on various TSP benchmark sets point out that the feature scaling succeeds in eliminating
    the effect of the instance size. A proof-of-concept AS-study shows promising results:
    models trained with normalized features tend to outperform those trained with
    the respective vanilla features.'

  text: 'Automated Algorithm Configuration (AAC) usually takes a global perspective:
    it identifies a parameter configuration for an (optimization) algorithm that maximizes
    a performance metric over a set of instances. However, the optimal choice of parameters
    strongly depends on the instance at hand and should thus be calculated on a per-instance
    basis. We explore the potential of Per-Instance Algorithm Configuration (PIAC)
    by using Reinforcement Learning (RL). To this end, we propose a novel PIAC approach
    that is based on deep neural networks. We apply it to predict configurations for
    the Lin\textendash Kernighan heuristic (LKH) for the Traveling Salesperson Problem
    (TSP) individually for every single instance. To train our PIAC approach, we create
    a large set of 100000 TSP instances with 2000 nodes each \textemdash currently
    the largest benchmark set to the best of our knowledge. We compare our approach
    to the state-of-the-art AAC method Sequential Model-based Algorithm Configuration
    (SMAC). The results show that our PIAC approach outperforms this baseline on both
    the newly created instance set and established instance sets.'

  text: ' Computational social science uses computational and statistical methods
    in order to evaluate social interaction. The public availability of data sets
    is thus a necessary precondition for reliable and replicable research. These data
    allow researchers to benchmark the computational methods they develop, test the
    generalizability of their findings, and build confidence in their results. When
    social media data are concerned, data sharing is often restricted for legal or
    privacy reasons, which makes the comparison of methods and the replicability of
    research results infeasible. Social media analytics research, consequently, faces
    an integrity crisis. How is it possible to create trust in computational or statistical
    analyses, when they cannot be validated by third parties? In this work, we explore
    this well-known, yet little discussed, problem for social media analytics. We
    investigate how this problem can be solved by looking at related computational
    research areas. Moreover, we propose and implement a prototype to address the
    problem in the form of a new evaluation framework that enables the comparison
    of algorithms without the need to exchange data directly, while maintaining flexibility
    for the algorithm design. '

  text: Hyperparameter optimization (HPO) is a key component of machine learning models
    for achieving peak predictive performance. While numerous methods and algorithms
    for HPO have been proposed over the last years, little progress has been made
    in illuminating and examining the actual structure of these black-box optimization
    problems. Exploratory landscape analysis (ELA) subsumes a set of techniques that
    can be used to gain knowledge about properties of unknown optimization problems.
    In this paper, we evaluate the performance of five different black-box optimizers
    on 30 HPO problems, which consist of two-, three- and five-dimensional continuous
    search spaces of the XGBoost learner trained on 10 different data sets. This is
    contrasted with the performance of the same optimizers evaluated on 360 problem
    instances from the black-box optimization benchmark (BBOB). We then compute ELA
    features on the HPO and BBOB problems and examine similarities and differences.
    A cluster analysis of the HPO and BBOB problems in ELA feature space allows us
    to identify how the HPO problems compare to the BBOB problems on a structural
    meta-level. We identify a subset of BBOB problems that are close to the HPO problems
    in ELA feature space and show that optimizer performance is comparably similar
    on these two sets of benchmark problems. We highlight open challenges of ELA for
    HPO and discuss potential directions of future research and applications.

  text: Single-objective continuous optimization can be challenging, especially when
    dealing with multimodal problems. This work sheds light on the effects that multi-objective
    optimization may have in the single-objective space. For this purpose, we examine
    the inner mechanisms of the recently developed sophisticated local search procedure
    SOMOGSA. This method solves multimodal single-objective continuous optimization
    problems based on first expanding the problem with an additional objective (e.g.,
    a sphere function) to the bi-objective domain and subsequently exploiting local
    structures of the resulting landscapes. Our study particularly focuses on the
    sensitivity of this multiobjectivization approach w.r.t. (1) the parametrization
    of the artificial second objective, as well as (2) the position of the initial
    starting points in the search space. As SOMOGSA is a modular framework for encapsulating
    local search, we integrate Nelder–Mead local search as optimizer in the respective
    module and compare the performance of the resulting hybrid local search to its
    original single-objective counterpart. We show that the SOMOGSA framework can
    significantly boost local search by multiobjectivization. Hence, combined with
    more sophisticated local search and metaheuristics, this may help solve highly
    multimodal optimization problems in the future.

  text: Generating instances of different properties is key to algorithm selection
    methods that differentiate between the performance of different solvers for a
    given combinatorial optimization problem. A wide range of methods using evolutionary
    computation techniques has been introduced in recent years. With this paper, we
    contribute to this area of research by providing a new approach based on quality
    diversity (QD) that is able to explore the whole feature space. QD algorithms
    allow to create solutions of high quality within a given feature space by splitting
    it up into boxes and improving solution quality within each box. We use our QD
    approach for the generation of TSP instances to visualize and analyze the variety
    of instances differentiating various TSP solvers and compare it to instances generated
    by established approaches from the literature.

  text: In multimodal multi-objective optimization (MMMOO), the focus is not solely
    on convergence in objective space, but rather also on explicitly ensuring diversity
    in decision space. We illustrate why commonly used diversity measures are not
    entirely appropriate for this task and propose a sophisticated basin-based evaluation
    (BBE) method. Also, BBE variants are developed, capturing the anytime behavior
    of algorithms. The set of BBE measures is tested by means of an algorithm configuration
    study. We show that these new measures also transfer properties of the well-established
    hypervolume (HV) indicator to the domain of MMMOO, thus also accounting for objective
    space convergence. Moreover, we advance MMMOO research by providing insights into
    the multimodal performance of the considered algorithms. Specifically, algorithms
    exploiting local structures are shown to outperform classical evolutionary multi-objective
    optimizers regarding the BBE variants and respective trade-off with HV.

  text: Recently different evolutionary computation approaches have been developed
    that generate sets of high quality diverse solutions for a given optimisation
    problem. Many studies have considered diversity 1) as a mean to explore niches
    in behavioural space (quality diversity) or 2) to increase the structural differences
    of solutions (evolutionary diversity optimisation). In this study, we introduce
    a co-evolutionary algorithm to simultaneously explore the two spaces for the multi-component
    traveling thief problem. The results show the capability of the co-evolutionary
    algorithm to achieve significantly higher diversity compared to the baseline evolutionary
    diversity algorithms from the literature.

  text: Due to the rise of continuous data-generating applications, analyzing data
    streams has gained increasing attention over the past decades. A core research
    area in stream data is stream classification, which categorizes or detects data
    points within an evolving stream of observations. Areas of stream classification
    are diverse\textemdash ranging, e.g., from monitoring sensor data to analyzing
    a wide range of (social) media applications. Research in stream classification
    is related to developing methods that adapt to the changing and potentially volatile
    data stream. It focuses on individual aspects of the stream classification pipeline,
    e.g., designing suitable algorithm architectures, an efficient train and test
    procedure, or detecting so-called concept drifts. As a result of the many different
    research questions and strands, the field is challenging to grasp, especially
    for beginners. This survey explores, summarizes, and categorizes work within the
    domain of stream classification and identifies core research threads over the
    past few years. It is structured based on the stream classification process to
    facilitate coordination within this complex topic, including common application
    scenarios and benchmarking data sets. Thus, both newcomers to the field and experts
    who want to widen their scope can gain (additional) insight into this research
    area and find starting points and pointers to more in-depth literature on specific
    issues and research directions in the field.

  text: Hardness of Multi-Objective (MO) continuous optimization problems results
    from an interplay of various problem characteristics, e. g. the degree of multi-modality.
    We present a benchmark study of classical and diversity focused optimizers on
    multi-modal MO problems based on automated algorithm configuration. We show the
    large effect of the latter and investigate the trade-off between convergence in
    objective space and diversity in decision space.

  text: Exploratory Landscape Analysis is a powerful technique for numerically characterizing
    landscapes of single-objective continuous optimization problems. Landscape insights
    are crucial both for problem understanding as well as for assessing benchmark
    set diversity and composition. Despite the irrefutable usefulness of these features,
    they suffer from their own ailments and downsides. Hence, in this work we provide
    a collection of different approaches to characterize optimization landscapes.
    Similar to conventional landscape features, we require a small initial sample.
    However, instead of computing features based on that sample, we develop alternative
    representations of the original sample. These range from point clouds to 2D images
    and, therefore, are entirely feature-free. We demonstrate and validate our devised
    methods on the BBOB testbed and predict, with the help of Deep Learning, the high-level,
    expert-based landscape properties such as the degree of multimodality and the
    existence of funnel structures. The quality of our approaches is on par with methods
    relying on the traditional landscape features. Thereby, we provide an exciting
    new perspective on every research area which utilizes problem information such
    as problem understanding and algorithm design as well as automated algorithm configuration
    and selection.

  text: In recent years, feature-based automated algorithm selection using exploratory
    landscape analysis has demonstrated its great potential in single-objective continuous
    black-box optimization. However, feature computation is problem-specific and can
    be costly in terms of computational resources. This paper investigates feature-free
    approaches that rely on state-of-the-art deep learning techniques operating on
    either images or point clouds. We show that point-cloud-based strategies, in particular,
    are highly competitive and also substantially reduce the size of the required
    solver portfolio. Moreover, we highlight the effect and importance of cost-sensitive
    learning in automated algorithm selection models.

  text: Social media platforms are essential for information sharing and, thus, prone
    to coordinated dis- and misinformation campaigns. Nevertheless, research in this
    area is hampered by strict data sharing regulations imposed by the platforms,
    resulting in a lack of benchmark data. Previous work focused on circumventing
    these rules by either pseudonymizing the data or sharing fragments. In this work,
    we will address the benchmarking crisis by presenting a methodology that can be
    used to create artificial campaigns out of original campaign building blocks.
    We conduct a proof-of-concept study using the freely available generative language
    model GPT-Neo in this context and demonstrate that the campaign patterns can flexibly
    be adapted to an underlying social media stream and evade state-of-the-art campaign
    detection approaches based on stream clustering. Thus, we not only provide a framework
    for artificial benchmark generation but also demonstrate the possible adversarial
    nature of such benchmarks for challenging and advancing current campaign detection
    methods.

  text: Due to the rise of continuous data-generating applications, analyzing data
    streams has gained increasing attention over the past decades. A core research
    area in stream data is stream classification, which categorizes or detects data
    points within an evolving stream of observations. Areas of stream classification
    are diverse—ranging, e.g., from monitoring sensor data to analyzing a wide range
    of (social) media applications. Research in stream classification is related to
    developing methods that adapt to the changing and potentially volatile data stream.
    It focuses on individual aspects of the stream classification pipeline, e.g.,
    designing suitable algorithm architectures, an efficient train and test procedure,
    or detecting so-called concept drifts. As a result of the many different research
    questions and strands, the field is challenging to grasp, especially for beginners.
    This survey explores, summarizes, and categorizes work within the domain of stream
    classification and identifies core research threads over the past few years. It
    is structured based on the stream classification process to facilitate coordination
    within this complex topic, including common application scenarios and benchmarking
    data sets. Thus, both newcomers to the field and experts who want to widen their
    scope can gain (additional) insight into this research area and find starting
    points and pointers to more in-depth literature on specific issues and research
    directions in the field.

  text: Hardness of Multi-Objective (MO) continuous optimization problems results
    from an interplay of various problem characteristics, e. g. the degree of multi-modality.
    We present a benchmark study of classical and diversity focused optimizers on
    multi-modal MO problems based on automated algorithm configuration. We show the
    large effect of the latter and investigate the trade-off between convergence in
    objective space and diversity in decision space.
