text: Plastic freeforming (PF) is an additive-manufacturing process for producing
three-dimensional plastic parts based on 3D CAD data by applying plastic droplets
in layers. This process is used to produce customer-specific and complex geometries
(prototypes and small series) on organic sheets. A comparable serial process is
the injection of a second component onto organic sheets by injection molding.
A sufficient bond between the PF structure and the organic sheets is of particular
importance for each application. If this is not guaranteed, the composite system
cannot withstand the mechanical load and fails. The force exerted on the system
can no longer be transmitted between the PF structure and the organic sheet. The
organic sheet is made of glass fiber-reinforced polypropylene (PP). The connection
between the organic sheet and the PF structure is achieved by welding the molten
polymer droplets and the surface of the organic sheet. The PF structures are made
of PP to ensure sufficient compatibility with regard to the weldability of the
components. The processing of PP in the PF process is a challenge because PP is
a semicrystalline material. The shrinkage of semi-crystalline materials is significantly
higher compared to amorphous materials. Due to the layered structure of the components,
the shrinkage of the individual layers results in undesired warpage. The adhesive
strength between the organic sheet and the PF structure is investigated by determining
the bending strength in the 3-point bending test. The investigations include an
optimization of the process parameters to maximize the adhesive strength. The
experimental investigations show that an increase of the nozzle and build chamber
temperature leads to a higher adhesive strength. In further investigations, the
temperature of the nozzle shows no significant influence on the surface temperature
despite the expected heat radiation. The surface temperature is almost only dependent
on the temperature of the build chamber.

text: The mechanical properties of thin-walled plastic components are limited. One
approach to improve the strength or stiffness of these components is to reinforce
the thin-walled areas with an individually adapted Fused Deposition Modeling structure.
Fused Deposition Modeling (FDM) is one of the most commonly used additive manufacturing
processes. This process is characterized by the deposition of a fused, thermoplastic
filament. Depending on the form of the reinforcement structure, the resulting
hybrid structure should show higher strength or stiffness. The objective of the
project is to determine constructive design and process guidelines for FDM structures.
The FDM structure is to be used as a partial reinforcement for lightweight components
and be adapted to the respective load conditions. Because of the lightweight application,
the FDM structure should also have the lowest possible weight. The optimization
of the FDM parts for different load cases is realized by adapting the design parameters.
These parameters influence the layer generation and therefore also the inner structure
of the FDM parts. In preliminary studies, the manufacturing restrictions of the
FDM process are defined. The specimens are manufactured based on the Design of
Experiments. To determine the static strength properties, different tests (tensile,
compression, flexural, torsion and impact) are carried out. The investigations
show that the filling strategy affects the mechanical properties. As a result
of the investigations, design and process guidelines for the FDM structures are
established according to the load conditions.

text: Employing main and sector-specific investment-grade CDS indices from the North
American and European CDS market and performing mean-variance out-of-sample analyses
for conservative and aggressive investors over the period from 2006 to 2014, this
paper analyzes portfolio benefits of adding corporate CDS indices to a traditional
financial portfolio consisting of stock and sovereign bond indices. As a baseline
result, we initially find an increase in portfolio (downside) risk-diversification
when adding CDS indices, which is observed irrespective of both CDS markets, investor-types
and different sub-periods, including the global financial crisis and European
sovereign debt crisis. In addition, the analysis reveals higher portfolio excess
returns and performance in CDS index portfolios, however, these effects clearly
differ between markets, investor-types and sub-periods. Overall, portfolio benefits
of adding CDS indices mainly result from the fact that institutional investors
replace sovereign bond indices rather than stock indices by CDS indices due to
better risk-return characteristics. Our baseline findings remain robust under
a variety of robustness checks. Results from sensitivity analyses provide further
important implications for institutional investors with a strategic focus on a
long-term conservative portfolio management.

text: While observational studies show an association between 25(OH)vitamin
D concentrations and depressive symptoms, intervention studies, which examine
the preventive effects of vitamin D supplementation on the development of depression,
are lacking. To estimate the role of lowered 25(OH)vitamin D concentrations in
the etiology of depressive disorders, we conducted a two-sample Mendelian randomization
(MR) study on depression, i.e., “depressive symptoms” (DS, n = 161,460) and “broad
depression” (BD, n = 113,769 cases and 208,811 controls). Six single nucleotide
polymorphisms (SNPs), which were genome-wide significantly associated with 25(OH)vitamin
D concentrations in 79,366 subjects from the SUNLIGHT genome-wide association
study (GWAS), were used as an instrumental variable. None of the six SNPs was
associated with DS or BD (all p > 0.05). MR analysis revealed no causal effects
of 25(OH)vitamin D concentration, either on DS (inverse variance weighted (IVW);
b = 0.025, SE = 0.038, p = 0.52) or on BD (IVW; b = 0.020, SE = 0.012, p = 0.10).
Sensitivity analyses confirmed that 25(OH)vitamin D concentrations were not significantly
associated with DS or BD. The findings from this MR study indicate no causal relationship
between vitamin D concentrations and depressive symptoms, or broad depression.
Conflicting findings from observational studies might have resulted from residual
confounding or reverse causation.

text: This paper addresses multimodality of multi-objective (MO) optimization landscapes.
Contrary to common perception of local optima, according to which they are hindering
the progress of optimization algorithms, it will be shown that local efficient
sets in a multi-objective setting can assist optimizers in finding global efficient
sets. We use sophisticated visualization techniques, which rely on gradient field
heatmaps, to highlight those insights into landscape characteristics. Finally,
the MO local optimizer MOGSA is introduced, which exploits those observations
by sliding down the multi-objective gradient hill and moving along the local efficient
sets.

text: There is a range of phenomena in continuous, global multi-objective optimization,
that cannot occur in single-objective optimization. For instance, in some multi-objective
optimization problems it is possible to follow continuous paths of gradients of
straightforward weighted scalarization functions, starting from locally efficient
solutions, in order to reach globally Pareto optimal solutions. This paper seeks
to better characterize multimodal multi-objective landscapes and to better understand
the transitions from local optima to global optima in simple, path-oriented search
procedures.

text: Choosing the best-performing optimizer(s) out of a portfolio of optimization
algorithms is usually a difficult and complex task. It gets even worse, if the
underlying functions are unknown, i.e., so-called black-box problems, and function
evaluations are considered to be expensive. In case of continuous single-objective
optimization problems, exploratory landscape analysis (ELA), a sophisticated and
effective approach for characterizing the landscapes of such problems by means
of numerical values before actually performing the optimization task itself, is
advantageous. Unfortunately, until now it has been quite complicated to compute
multiple ELA features simultaneously, as the corresponding code has been—if at
all—spread across multiple platforms or at least across several packages within
these platforms. This article presents a broad summary of existing ELA approaches
and introduces flacco, an R-package for feature-based landscape analysis of continuous
and constrained optimization problems. Although its functions neither solve the
optimization problem itself nor the related algorithm selection problem (ASP),
it offers easy access to an essential ingredient of the ASP by providing a wide
collection of ELA features on a single platform—even within a single package.
In addition, flacco provides multiple visualization techniques, which enhance
the understanding of some of these numerical features, and thereby make certain
landscape properties more comprehensible. On top of that, we will introduce the
package’s built-in, as well as web-hosted and hence platform-independent, graphical
user interface (GUI). It facilitates the usage of the package—especially for people
who are not familiar with R—and thus makes flacco a very convenient toolbox when
working towards algorithm selection of continuous single-objective optimization
problems.

text: In this article, we build upon previous work on designing informative and
efficient Exploratory Landscape Analysis features for characterizing problems'
landscapes and show their effectiveness in automatically constructing algorithm
selection models in continuous black-box optimization problems. Focusing on algorithm
performance results of the COCO platform of several years, we construct a representative
set of high-performing complementary solvers and present an algorithm selection
model that, compared to the portfolio's single best solver, on average requires
less than half of the resources for solving a given problem. Therefore, there
is a huge gain in efficiency compared to classical ensemble methods combined with
an increased insight into problem characteristics and algorithm properties by
using informative features. The model acts on the assumption that the function
set of the Black-Box Optimization Benchmark is representative enough for practical
applications. The model allows for selecting the best suited optimization algorithm
within the considered set for unseen problems prior to the optimization itself
based on a small sample of function evaluations. Note that such a sample can even
be reused for the initial population of an evolutionary (optimization) algorithm
so that even the feature costs become negligible.

text: We continue recent work on the definition of multimodality in multiobjective
optimization (MO) and the introduction of a test bed for multimodal MO problems.
This goes beyond well-known diversity maintenance approaches but instead focuses
on the landscape topology induced by the objective functions. More general multimodal
MO problems are considered by allowing ellipsoid contours for single-objective
subproblems. An experimental analysis compares two MO algorithms, one that explicitly
relies on hypervolume gradient approximation, and one that is based on local search,
both on a selection of generated example problems. We do not focus on performance
but on the interaction induced by the problems and algorithms, which can be described
by means of specific characteristics explicitly designed for the multimodal MO
setting. Furthermore, we widen the scope of our analysis by additionally applying
visualization techniques in the decision space. This strengthens and extends the
foundations for Exploratory Landscape Analysis (ELA) in MO.

text: We tackle a bi-objective dynamic orienteering problem where customer requests
arise as time passes by. The goal is to minimize the tour length traveled by a
single delivery vehicle while simultaneously keeping the number of dismissed dynamic
customers to a minimum. We propose a dynamic Evolutionary Multi-Objective Algorithm
which is grounded on insights gained from a previous series of work on an a-posteriori
version of the problem, where all request times are known in advance. In our experiments,
we simulate different decision maker strategies and evaluate the development of
the Pareto-front approximations on exemplary problem instances. It turns out,
that despite severely reduced computational budget and no oracle-knowledge of
request times the dynamic EMOA is capable of producing approximations which partially
dominate the results of the a-posteriori EMOA and dynamic integer linear programming
strategies.

text: 'Evolutionary algorithms have successfully been applied to evolve problem
instances that exhibit a significant difference in performance for a given algorithm
or a pair of algorithms inter alia for the Traveling Salesperson Problem (TSP).
Creating a large variety of instances is crucial for successful applications in
the blooming field of algorithm selection. In this paper, we introduce new and
creative mutation operators for evolving instances of the TSP. We show that adopting
those operators in an evolutionary algorithm allows for the generation of benchmark
sets with highly desirable properties: (1) novelty by clear visual distinction
to established benchmark sets in the field, (2) visual and quantitative diversity
in the space of TSP problem characteristics, and (3) significant performance differences
with respect to the restart versions of heuristic state-of-the-art TSP solvers
EAX and LKH. The important aspect of diversity is addressed and achieved solely
by the proposed mutation operators and not enforced by explicit diversity preservation.'
