text: Cyanobacteriochromes are compact and spectrally diverse photoreceptor
proteins that are promising candidates for biotechnological applications. Computational
studies can contribute to an understanding at a molecular level of their wide
spectral tuning and diversity. In this contribution, we benchmark methods to model
a 110 nm shift in the UV/Vis absorption spectrum from a red- to a green-absorbing
form of the cyanobacteriochrome Slr1393g3. Based on an assessment of semiempirical
methods to describe the chromophore geometries of both forms in vacuo, we find
that DFTB2+D leads to structures that are the closest to the reference method.
The benchmark of the excited state calculations is based on snapshots from quantum
mechanics/molecular mechanics molecular dynamics simulations. In our case, the
methods RI-ADC(2) and sTD-DFT based on CAM-B3LYP ground state calculations perform
the best, whereas no functional can be recommended to simulate the absorption
spectra of both forms with time-dependent density functional theory. Furthermore,
the difference in absorption for the lowest energy absorption maxima of both forms
can already be modelled with optimized structures, but sampling is required to
improve the shape of the absorption bands of both forms, in particular for the
second band. This benchmark study can guide further computational studies, as
it assesses essential components of a protocol to model the spectral tuning of
both cyanobacteriochromes and the related phytochromes.

text: "State-of-the-art frameworks for generating approximate circuits automatically
explore the search space in an iterative process - often greedily. Synthesis and
verification processes are invoked in each iteration to evaluate the found solutions
and to guide the search algorithm. As a result, a large number of approximate
circuits is subjected to analysis - leading to long runtimes - but only a few
approximate circuits might form an acceptable solution.\r\n\r\nIn this paper,
we present our Jump Search (JS) method which seeks to reduce the runtime of an
approximation process by reducing the number of expensive synthesis and verification
steps. To reduce the runtime, JS computes impact factors for each approximation
candidate in the circuit to create a selection of approximate circuits without
invoking synthesis or verification processes. We denote the selection as path
from which JS determines the final solution. In our experimental results, JS achieved
speed-ups of up to 57x while area savings remain comparable to the reference search
method, Simulated Annealing."

text: We consider the problem of transforming a given graph G_s into a desired graph
G_t by applying a minimum number of primitives from a particular set of local
graph transformation primitives. These primitives are local in the sense that
each node can apply them based on local knowledge and by affecting only its 1-neighborhood.
Although the specific set of primitives we consider makes it possible to transform
any (weakly) connected graph into any other (weakly) connected graph consisting
of the same nodes, they cannot disconnect the graph or introduce new nodes into
the graph, making them ideal in the context of supervised overlay network transformations.
We prove that computing a minimum sequence of primitive applications (even centralized)
for arbitrary G_s and G_t is NP-hard, which we conjecture to hold for any set
of local graph transformation primitives satisfying the aforementioned properties.
On the other hand, we show that this problem admits a polynomial time algorithm
with a constant approximation ratio.

text: We present a new framework for optimal and feedback control of PDEs using
Koopman operator-based reduced order models (K-ROMs). The Koopman operator is
a linear but infinite-dimensional operator which describes the dynamics of observables.
A numerical approximation of the Koopman operator therefore yields a linear system
for the observation of an autonomous dynamical system. In our approach, by introducing
a finite number of constant controls, the dynamic control system is transformed
into a set of autonomous systems and the corresponding optimal control problem
into a switching time optimization problem. This allows us to replace each of
these systems by a K-ROM which can be solved orders of magnitude faster. By this
approach, a nonlinear infinite-dimensional control problem is transformed into
a low-dimensional linear problem. Using a recent convergence result for the numerical
approximation via Extended Dynamic Mode Decomposition (EDMD), we show that the
value of the K-ROM based objective function converges in measure to the value
of the full objective function. To illustrate the results, we consider the 1D
Burgers equation and the 2D Navier–Stokes equations. The numerical experiments
show remarkable performance concerning both solution times and accuracy.

text: In this article we show that the boundary of the Pareto critical set of an
unconstrained multiobjective optimization problem (MOP) consists of Pareto critical
points of subproblems where only a subset of the set of objective functions is
taken into account. If the Pareto critical set is completely described by its
boundary (e.g., if we have more objective functions than dimensions in decision
space), then this can be used to efficiently solve the MOP by solving a number
of MOPs with fewer objective functions. If this is not the case, the results can
still give insight into the structure of the Pareto critical set.
