PPSZ is better than you think
Dominik Scheder
PPSZ, for long time the fastest known algorithm for -SAT, works by going through the variables of the input formula in random order; each variable is then set randomly to or…
Poly(ionic liquid)s: platform for CO2 capture and catalysis
Xianjing Zhou, Jens Weber, Jiayin Yuan
Capture and conversion of CO2 are of great importance for environment-friendly and sustainable development of human society. Poly(ionic liquid)s (PILs) combine some unique properti…
Optimization problem for a portfolio with an illiquid asset: Lie group analysis
Ljudmila A. Bordag, Ivan P. Yamshchikov
Management of a portfolio that includes an illiquid asset is an important problem of modern mathematical finance. One of the ways to model illiquidity among others is to build an o…
Portfolio optimization in the case of an asset with a given liquidation time distribution
Ljudmila A. Bordag, Ivan P. Yamshchikov, Dmitry Zhelezov
Management of the portfolios containing low liquidity assets is a tedious problem. The buyer proposes the price that can differ greatly from the paper value estimated by the seller…
Aircraft Landing Problem: Efficient Algorithm for a Given Landing Sequence
Abhishek Awasthi, Oliver Kramer, Jörg Lässig
In this paper, we investigate a special case of the static aircraft landing problem (ALP) with the objective to optimize landing sequences and landing times for a set of air planes…
Analysis of Speedups in Parallel Evolutionary Algorithms for Combinatorial Optimization
Jörg Lässig, Dirk Sudholt
Evolutionary algorithms are popular heuristics for solving various combinatorial problems as they are easy to apply and often produce good results. Island models parallelize evolut…
Implicit iteration methods in Hilbert scales under general smoothness conditions
Qinian Jin, Ulrich Tautenhahn
For solving linear ill-posed problems regularization methods are required when the right hand side is with some noise. In the present paper regularized solutions are obtained by im…
Inexact Newton regularization methods in Hilbert scales
Qinian Jin, Ulrich Tautenhahn
We consider a class of inexact Newton regularization methods for solving nonlinear inverse problems in Hilbert scales. Under certain conditions we obtain the order optimal converge…
On the discrepancy principle for some Newton type methods for solving nonlinear inverse problems
Qinian Jin, Ulrich Tautenhahn
We consider the computation of stable approximations to the exact solution of nonlinear ill-posed inverse problems with nonlinear operators between two Hi…
