text: Besides the life-as-it-could-be driver of artificial life research there is
also the concept of extending natural life by creating hybrids or mixed societies
that are built from natural and artificial components. In this paper we motivate
and present the research program of the project flora robotica. Our objective
is to develop and to investigate closely linked symbiotic relationships between
robots and natural plants and to explore the potentials of a plant-robot society
able to produce architectural artifacts and living spaces. These robot-plant bio-hybrids
create synergies that allow for new functions of plants and robots. They also
create novel design opportunities for an architecture that fuses the design and
construction phase. The bio-hybrid is an example of mixed societies between 'hard'
artificial and 'wet' natural life, which enables an interaction between natural
and artificial ecologies. They form an embodied, self-organizing, and distributed
cognitive system which is supposed to grow and develop over long periods of time
resulting in the creation of meaningful architectural structures. A key idea is
to assign equal roles to robots and plants in order to create a highly integrated,
symbiotic system. Besides the gain of knowledge, this project has the objective
to create a bio-hybrid system with a defined function and application -- growing
architectural artifacts.

text: Recent approaches in evolutionary robotics (ER) propose to generate behavioral
diversity in order to evolve desired behaviors more easily. These approaches require
the definition of a behavioral distance, which often includes task-specific features
and hence a priori knowledge. Alternative methods, which do not explicitly force
selective pressure towards diversity (SPTD) but still generate it, are known from
the field of artificial life, such as in artificial ecologies (AEs). In this study,
we investigate how SPTD is generated without task-specific behavioral features
or other forms of a priori knowledge and detect how methods of generating SPTD
can be transferred from the domain of AE to ER. A promising finding is that in
both types of systems, in systems from ER that generate behavioral diversity and
also in the investigated speciation model, selective pressure is generated towards
unpopulated regions of search space. In a simple case study we investigate the
practical implications of these findings and point to options for transferring
the idea of self-organizing SPTD in AEs to the domain of ER.

text: Aggregation is a crucial task in swarm robotics to ensure cooperation. We
investigate the task of aggregation on an area specified indirectly by certain
environmental features, here it is a light distribution. We extend the original
BEECLUST algorithm, that implements an aggregation behavior, to an adaptive variant
that automatically adapts to any light conditions. We compare these two control
algorithms in a number of swarm robot experiments with different light conditions.
The improved, adaptive variant is found to be significantly better in the tested
setup.

text: Fitness function design is known to be a critical feature of the evolutionary-robotics
approach. Potentially, the complexity of evolving a successful controller for
a given task can be reduced by integrating a priori knowledge into the fitness
function which complicates the comparability of studies in evolutionary robotics.
Still, there are only few publications that study the actual effects of different
fitness functions on the robot's performance. In this paper, we follow the fitness
function classification of Nelson et al. (2009) and investigate a selection of
four classes of fitness functions that require different degrees of a priori knowledge.
The robot controllers are evolved in simulation using NEAT and we investigate
different tasks including obstacle avoidance and (periodic) goal homing. The best
evolved controllers were then post-evaluated by examining their potential for
adaptation, determining their convergence rates, and using cross-comparisons based
on the different fitness function classes. The results confirm that the integration
of more a priori knowledge can simplify a task and show that more attention should
be paid to fitness function classes when comparing different studies.

text: The Collaborative Research Centre "On-The-Fly Computing" works on foundations
and principles for the vision of the Future Internet. It proposes the paradigm
of On-The-Fly Computing, which tackles emerging worldwide service markets. In
these markets, service providers trade software, platform, and infrastructure
as a service. Service requesters state requirements on services. To satisfy these
requirements, the new role of brokers, who are (human) actors building service
compositions on the fly, is introduced. Brokers have to specify service compositions
formally and comprehensively using a domain-specific language (DSL), and to use
service matching for the discovery of the constituent services available in the
market. The broker's choice of the DSL and matching approaches influences her
success of building compositions as distinctive properties of different service
markets play a significant role. In this paper, we propose a new approach of engineering
a situation-specific DSL by customizing a comprehensive, modular DSL and its matching
for given service market properties. This enables the broker to create market-specific
composition specifications and to perform market-specific service matching. As
a result, the broker builds service compositions satisfying the requester's requirements
more accurately. We evaluated the presented concepts using case studies in service
markets for tourism and university management.

text: Today, software verification is an established analysis method which can provide
high guarantees for software safety. However, the resources (time and/or memory)
for an exhaustive verification are not always available, and analysis then has
to resort to other techniques, like testing. Most often, the already achieved
partial verification results arediscarded in this case, and testing has to start
from scratch.In this paper, we propose a method for combining verification and
testing in which testing only needs to check the residual fraction of an uncompleted
verification. To this end, the partial results of a verification run are used
to construct a residual program (and residual assertions to be checked on it).
The residual program can afterwards be fed into standardtesting tools. The proposed
technique is sound modulo the soundness of the testing procedure. Experimental
results show that this combinedusage of verification and testing can significantly
reduce the effort for the subsequent testing.

text: In this work, we present the first scalable distributed information system,
that is, a system with low storage overhead, that is provably robust against denial-of-service
(DoS) attacks by a current insider. We allow a current insider to have complete
knowledge about the information system and to have the power to block any ϵ-fraction
of its servers by a DoS attack, where ϵ can be chosen up to a constant. The task
of the system is to serve any collection of lookup requests with at most one per
nonblocked server in an efficient way despite this attack. Previously, scalable
solutions were only known for DoS attacks of past insiders, where a past insider
only has complete knowledge about some past time point t0 of the information system.
Scheideler et al. [Awerbuch and Scheideler 2007; Baumgart et al. 2009] showed
that in this case, it is possible to design an information system so that any
information that was inserted or last updated after t0 is safe against a DoS attack.
But their constructions would not work at all for a current insider. The key idea
behind our IRIS system is to make extensive use of coding. More precisely, we
present two alternative distributed coding strategies with an at most logarithmic
storage overhead that can handle up to a constant fraction of blocked servers.

text: We propose an incremental workflow for the verification of parameterized systems
modeled as symmetric networks of timed automata. Starting with a small number
of timed automata in the network, a safety property is verified using IC3, a state-of-the-art
algorithm based on induction.The result of the verification, an inductive strengthening,
is reused proposing a candidate inductive strengthening for a larger network.If
the candidate is valid, our main theorem states that the safety property holds
for all sizes of the network of timed automata. Otherwise the number of automata
is increased and the next iteration is started with a new run of IC3.We propose
and thoroughly examine optimizations to our workflow, e.g. Feedback mechanisms
to speed up the run of IC3.

text: The size of modern data centers is constantly increasing. As it is not economic
to interconnect all machines in the data center using a full-bisection-bandwidth
network, techniques have to be developed to increase the efficiency of data-center
networks. The Software-Defined Network paradigm opened the door for centralized
traffic engineering (TE) in such environments. Up to now, there were already a
number of TE proposals for SDN-controlled data centers that all work very well.
However, these techniques either use a high amount of flow table entries or a
high flow installation rate that overwhelms available switching hardware, or they
require custom or very expensive end-of-line equipment to be usable in practice.
We present HybridTE, a TE technique that uses (uncertain) information about large
flows. Using this extra information, our technique has very low hardware requirements
while maintaining better performance than existing TE techniques. This enables
us to build very low-cost, high performance data-center networks.

text: Distributed applications are commonly based on overlay networks interconnecting
their sites so that they can exchange information. For these overlay networks
to preserve their functionality, they should be able to recover from various problems
like membership changes or faults. Various self-stabilizing overlay networks have
already been proposed in recent years, which have the advantage of being able
to recover from any illegal state, but none of these networks can give any guarantees
on its functionality while the recovery process is going on. We initiate research
on overlay networks that are not only self-stabilizing but that also ensure that
searchability is maintained while the recovery process is going on, as long as
there are no corrupted messages in the system. More precisely, once a search message
from node u to another node v is successfully delivered, all future search messages
from u to v succeed as well. We call this property monotonic searchability. We
show that in general it is impossible to provide monotonic searchability if corrupted
messages are present in the system, which justifies the restriction to system
states without corrupted messages. Furthermore, we provide a self-stabilizing
protocol for the line for which we can also show monotonic searchability. It turns
out that even for the line it is non-trivial to achieve this property. Additionally,
we extend our protocol to deal with node departures in terms of the Finite Departure
Problem of Foreback et. al (SSS 2014). This makes our protocol even capable of
handling node dynamics.
