  text: Despite the intrinsic hardness of the Traveling Salesperson Problem (TSP)
    heuristic solvers, e.g., LKH+restart and EAX+restart, are remarkably successful
    in generating satisfactory or even optimal solutions. However, the reasons for
    their success are not yet fully understood. Recent approaches take an analytical
    viewpoint and try to identify instance features, which make an instance hard or
    easy to solve. We contribute to this area by generating instance sets for couples
    of TSP algorithms A and B by maximizing/minimizing their performance difference
    in order to generate instances which are easier to solve for one solver and much
    harder to solve for the other. This instance set offers the potential to identify
    key features which allow to distinguish between the problem hardness classes of
    both algorithms.

  text: State of the Art inexact solvers of the NP-hard Traveling Salesperson Problem
    TSP are known to mostly yield high-quality solutions in reasonable computation
    times. With the purpose of understanding different levels of instance difficulties,
    instances for the current State of the Art heuristic TSP solvers LKH+restart and
    EAX+restart are presented which are evolved using a sophisticated evolutionary
    algorithm. More specifically, the performance differences of the respective solvers
    are maximized resulting in instances which are easier to solve for one solver
    and much more difficult for the other. Focusing on both optimization directions,
    instance features are identified which characterize both types of instances and
    increase the understanding of solver performance differences.

  text: The need for automatic methods of topic discovery in the Internet grows exponentially
    with the amount of available textual information. Nowadays it becomes impossible
    to manually read even a small part of the information in order to reveal the underlying
    topics. Social media provide us with a great pool of user generated content, where
    topic discovery may be extremely useful for businesses, politicians, researchers,
    and other stakeholders. However, conventional topic discovery methods, which are
    widely used in large text corpora, face several challenges when they are applied
    in social media and particularly in Twitter – the most popular microblogging platform.
    To the best of our knowledge no comprehensive overview of these challenges and
    of the methods dedicated to address these challenges does exist in IS literature
    until now. Therefore, this paper provides an overview of these challenges, matching
    methods and their expected usefulness for social media analytics.

  text: In single-objective optimization different optimization strategies exist depending
    on the structure and characteristics of the underlying problem. In particular,
    the presence of so-called funnels in multimodal problems offers the possibility
    of applying techniques exploiting the global structure of the function. The recently
    proposed Exploratory Landscape Analysis approach automatically identifies problem
    characteristics based on a moderately small initial sample of the objective function
    and proved to be effective for algorithm selection problems in continuous black-box
    optimization. In this paper, specific features for detecting funnel structures
    are introduced and combined with the existing ones in order to classify optimization
    problems regarding the funnel property. The effectiveness of the approach is shown
    by experiments on specifically generated test instances and validation experiments
    on standard benchmark problems.

  text: We investigate per-instance algorithm selection techniques for solving the
    Travelling Salesman Problem (TSP), based on the two state-of-the-art inexact TSP
    solvers, LKH and EAX. Our comprehensive experiments demonstrate that the solvers
    exhibit complementary performance across a diverse set of instances, and the potential
    for improving the state of the art by selecting between them is significant. Using
    TSP features from the literature as well as a set of novel features, we show that
    we can capitalise on this potential by building an efficient selector that achieves
    significant performance improvements in practice. Our selectors represent a significant
    improvement in the state-of-the-art in inexact TSP solving, and hence in the ability
    to find optimal solutions (without proof of optimality) for challenging TSP instances
    in practice.

  text: In multiobjective optimization, set-based performance indicators are commonly
    used to assess the quality of a Pareto front approximation. Based on the scalarization
    obtained by these indicators, a performance comparison of multiobjective optimization
    algorithms becomes possible. The R2 and the Hypervolume (HV) indicator represent
    two recommended approaches which have shown a correlated behavior in recent empirical
    studies. Whereas the HV indicator has been comprehensively analyzed in the last
    years, almost no studies on the R2 indicator exist. In this extended version of
    our previous conference paper, we thus perform a comprehensive investigation of
    the properties of the R2 indicator in a theoretical and empirical way. The influence
    of the number and distribution of the weight vectors on the optimal distribution
    of µ solutions is analyzed. Based on a comparative analysis, specific characteristics
    and differences of the R2 and HV indicator are presented. Furthermore, the R2
    indicator is integrated into an indicator-based steady-state evolutionary multiobjective
    optimization algorithm (EMOA). It is shown that the so-called R2-EMOA can accurately
    approximate the optimal distribution of µ solutions regarding R2.

  text: "We consider a routing problem for a single vehicle serving customer Locations
    in the course of time. A subset of these customers must necessarily be served,
    while the complement of this subset contains dynamic customers which request for
    service over time, and which do not necessarily need to be served. The decision
    maker’s conflicting goals are serving as many customers as possible as well as
    minimizing total travel distance. We solve this bi-objective Problem with an evolutionary
    multi-objective algorithm in order to provide an a-posteriori evaluation tool
    for enabling decision makers to assess the single objective solution strategies
    that they actually use in real-time. We present the modifications to be applied
    to the evolutionary multi-objective algorithm NSGA2 in order to solve the routing
    problem, we describe a number of real-time single-objective solution strategies,
    and we finally use the gained efficient trade-off solutions of NSGA2 to exemplarily
    evaluate the real-time strategies. Our results show that the evolutionary multi-objective
    approach is well-suited to generate benchmarks for assessing dynamic heuristic
    strategies. Our findings point into future directions for designing dynamic multi-objective
    approaches for the vehicle routing problem with time windows.\r\n"

  text: 'We present methods to answer two basic questions that arise when benchmarking
    optimization algorithms. The first one is: which algorithm is the "best" one?
    and the second one is: which algorithm should I use for my real-world problem?
    Both are connected and neither is easy to answer. We present a theoretical framework
    for designing and analyzing the raw data of such benchmark experiments. This represents
    a first step in answering the aforementioned questions. The 2009 and 2010 BBOB
    benchmark results are analyzed by means of this framework and we derive insight
    regarding the answers to the two questions. Furthermore, we discuss how to properly
    aggregate rankings from algorithm evaluations on individual problems into a consensus,
    its theoretical background and which common pitfalls should be avoided. Finally,
    we address the grouping of test problems into sets with similar optimizer rankings
    and investigate whether these are reflected by already proposed test problem characteristics,
    finding that this is not always the case.'

    exploration of the parameter space is tedious – even for few parameters – several
    automatic procedures for parameter tuning have been proposed. Recent approaches
    also take into account some characteristic properties of the problem instances,
    frequently termed instance features. Our contribution is the proposal of a novel
    concept for feature-based algorithm parameter tuning, which applies an approximating
    surrogate model for learning the continuous feature-parameter mapping. To accomplish
    this, we learn a joint model of the algorithm performance based on both the algorithm
    parameters and the instance features. The required data is gathered using a recently
    proposed acquisition function for model refinement in surrogate-based optimization:
    the profile expected improvement. This function provides an avenue for maximizing
    the information required for the feature-parameter mapping, i.e., the mapping
    from instance features to the corresponding optimal algorithm parameters. The
    approach is validated by applying the tuner to exemplary evolutionary algorithms
    and problems, for which theoretically grounded or heuristically determined feature-parameter
    mappings are available.'

  text: 'We evaluate the performance of a multi-objective evolutionary algorithm on
    a class of dynamic routing problems with a single vehicle. In particular we focus
    on relating algorithmic performance to the most prominent characteristics of problem

  text: Exploratory Landscape Analysis is an effective and sophisticated approach
    to characterize the properties of continuous optimization problems. The overall
    aim is to exploit this knowledge to give recommendations of the individually best
    suited algorithm for unseen optimization problems. Recent research revealed a
    high potential of this methodology in this respect based on a set of well-defined,
    computable features which only requires a quite small sample of function evaluations.
    In this paper, new features based on the cell mapping concept are introduced and
    shown to improve the existing feature set in terms of predicting expert-designed
    high-level properties, such as the degree of multimodality or the global structure,
    for 2-dimensional single objective optimization problems.

  text: The incorporation of expert knowledge into multiobjective optimization is
    an important issue which in this paper is reflected in terms of an aspiration
    set consisting of multiple reference points. The behaviour of the recently introduced
    evolutionary multiobjective algorithm AS-EMOA is analysed in detail and comparatively
    studied for bi-objective optimization problems w.r.t. R-NSGA2 and a respective
    variant. It will be shown that the averaged Hausdorff distance, integrated into
    AS-EMOA, is an efficient means to accurately approximate the desired aspiration
    set.

  text: Multimodal optimization requires maintenance of a good search space coverage
    and approximation of several optima at the same time. We analyze two constitutive
    optimization algorithms and show that in many cases, a phase transition occurs
    at some point, so that either diversity collapses or optimization stagnates. But
    how to derive suitable stopping criteria for multimodal optimization? Experimental
    results indicate that an algorithm’s population contains sufficient information
    to estimate the point in time when several performance indicators reach their
    optimum. Thus, stopping criteria are formulated based on summary characteristics
    employing objective values and mutation strength.

  text: "In many applications one is faced with the problem that multiple objectives
    have to be optimized at the same time. Since typically the solution set of such
    multi-objective optimization problems forms a manifold which cannot be computed
    analytically, one is in many cases interested in a suitable finite size approximation
    of this set. One widely used approach is to find a representative set that maximizes
    the dominated hypervolume that is defined by the images in objective space of
    these solutions and a given reference point.\r\n\r\nIn this paper, we propose
    a new point-wise iterative search procedure, Hypervolume Directed Search (HVDS),
    that aims to increase the hypervolume of a given point in an archive for bi-objective
    unconstrained optimization problems. We present the HVDS both as a standalone
    algorithm and as a local searcher within a specialized evolutionary algorithm.
    Numerical results confirm the strength of the novel approach."

  text: The averaged Hausdorff distance Δ p is a performance indicator in multi-objective
    evolutionary optimization which simultaneously takes into account proximity to
    the true Pareto front and uniform spread of solutions. Recently, the multi-objective
    evolutionary algorithm Δ p -EMOA was introduced which successfully generates evenly
    spaced Pareto front approximations for bi-objective problems by integrating an
    external archiving strategy into the SMS-EMOA based on Δ p . In this work a conceptual
    generalization of the Δ p -EMOA for higher objective space dimensions is presented
    and experimentally compared to state-of-the art EMOA as well as specialized EMOA
    variants on three-dimensional optimization problems.

  text: Understanding the behaviour of well-known algorithms for classical NP-hard
    optimisation problems is still a difficult task. With this paper, we contribute
    to this research direction and carry out a feature based comparison of local search
    and the well-known Christofides approximation algorithm for the Traveling Salesperson
    Problem. We use an evolutionary algorithm approach to construct easy and hard
    instances for the Christofides algorithm, where we measure hardness in terms of
    approximation ratio. Our results point out important features and lead to hard
    and easy instances for this famous algorithm. Furthermore, our cross-comparison
    gives new insights on the complementary benefits of the different approaches.
