  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: 'The majority of algorithms can be controlled or adjusted by parameters. Their
    values can substantially affect the algorithms’ performance. Since the manual
    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
    instances. The routing problem considers two types of customers: mandatory customers
    must be visited whereas optional customers do not necessarily have to be visited.
    Moreover, mandatory customers are known prior to the start of the tour whereas
    optional customers request for service at later points in time with the vehicle
    already being on its way. The multi-objective optimization problem then results
    as maximizing the number of visited customers while simultaneously minimizing
    total travel time. As an a-posteriori evaluation tool, the evolutionary algorithm
    aims at approximating the related Pareto set for specifically designed benchmarking
    instances differing in terms of number of customers, geographical layout, fraction
    of mandatory customers, and request times of optional customers. Conceptional
    and experimental comparisons to online heuristic procedures are provided.'
