text: In software engineering, the imprecise requirements of a user are transformed
to a formal requirements specification during the requirements elicitation process.
This process is usually guided by requirements engineers interviewing the user.
We want to partially automate this first step of the software engineering process
in order to enable users to specify a desired software system on their own. With
our approach, users are only asked to provide exemplary behavioral descriptions.
The problem of synthesizing a requirements specification from examples can partially
be reduced to the problem of grammatical inference, to which we apply an active
coevolutionary learning approach. However, this approach would usually require
many feedback queries to be sent to the user. In this work, we extend and generalize
our active learning approach to receive knowledge from multiple oracles, also
known as proactive learning. The ‘user oracle’ represents input received from
the user and the ‘knowledge oracle’ represents available, formalized domain knowledge.
We call our two-oracle approach the ‘first apply knowledge then query’ (FAKT/Q)
algorithm. We compare FAKT/Q to the active learning approach and provide an extensive
benchmark evaluation. As result we find that the number of required user queries
is reduced and the inference process is sped up significantly. Finally, with so-called
On-The-Fly Markets, we present a motivation and an application of our approach
where such knowledge is available.

text: Bridging the gap between informal, imprecise, and vague user requirements
descriptions and precise formalized specifications is the main task of requirements
engineering. Techniques such as interviews or story telling are used when requirements
engineers try to identify a user's needs. The requirements specification process
is typically done in a dialogue between users, domain experts, and requirements
engineers. In our research, we aim at automating the specification of requirements.
The idea is to distinguish between untrained users and trained users, and to exploit
domain knowledge learned from previous runs of our system. We let untrained users
provide unstructured natural language descriptions, while we allow trained users
to provide examples of behavioral descriptions. In both cases, our goal is to
synthesize formal requirements models similar to statecharts. From requirements
specification processes with trained users, behavioral ontologies are learned
which are later used to support the requirements specification process for untrained
users. Our research method is original in combining natural language processing
and search-based techniques for the synthesis of requirements specifications.
Our work is embedded in a larger project that aims at automating the whole software
development and deployment process in envisioned future software service markets.

text: The self-organizing bio-hybrid collaboration ofrobots and natural plants allows
for a variety of interestingapplications. As an example we investigate how robots
can beused to control the growth and motion of a natural plant, using LEDs to
provide stimuli. We follow an evolutionaryrobotics approach where task performance
is determined bymonitoring the plant's reaction. First, we do initial plantexperiments
with simple, predetermined controllers. Then weuse image sampling data as a model
of the dynamics ofthe plant tip xy position. Second, we use this approach toevolve
robot controllers in simulation. The task is to makethe plant approach three predetermined,
distinct points in anxy-plane. Finally, we test the evolved controllers in real
plantexperiments and find that we cross the reality gap successfully. We shortly
describe how we have extended from plant tipto many points on the plant, for a
model of the plant stemdynamics. Future work will extend to two-axes image samplingfor
a 3-d approach.

abstract:
- lang: eng
text: We apply methods of genetic programming to a general problem from software
engineering, namely example-based generation of specifications. In particular,
we focus on model transformation by example. The definition and implementation
of model transformations is a task frequently carried out by domain experts, hence,
a (semi-)automatic approach is desirable. This application is challenging because
the underlying search space has rich semantics, is high-dimensional, and unstructured.
Hence, a computationally brute-force approach would be unscalable and potentially
infeasible. To address that problem, we develop a sophisticated approach of designing
complex mutation operators. We define ‘patterns’ for constructing mutation operators
and report a successful case study. Furthermore, the code of the evolved model
transformation is required to have high maintainability and extensibility, that
is, the code should be easily readable by domain experts. We report an evaluation
of this approach in a software engineering case study.

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.
