Low-level features gathered by systematic sampling of the function on the feasible set are used to predict a well-performing algorithm out of a given portfolio. Example-specific label costs are defined by the expected runtime of each candidate algorithm. We use one-sided support vector regression to solve this learning problem.

For this process compounding extruders are used which mostly involve tightly intermeshing, co-rotating twin screw extruders. These extruders consist of two closely spaced screws which rotate in the same direction and convey the raw material to the screw tip. These screws are surrounded by several barrel modules which heat or cool the material. As the whole design of the machine is modularly arranged the process behavior of a twin screw extruder depends for the main part on the arrangement of the screw and the barrel elements. Until today this arrangement and process optimization is conducted by experienced engineers and with the help of trial-and-error methods. Furthermore, theoretical models are used with which the behavior of the extruder is estimated. As these models are mostly very complex they are only made available with the realization in different software projects. One of the tools is called SIGMA. Within this paper SIGMA is introduced as a software to optimize a twin screw extruder. SIGMA supports the engineer already in the early stages of the extruder arrangement.","lang":"eng"}],"status":"public","publisher":"Society for Computer Simulation International","date_updated":"2022-01-06T06:56:02Z","author":[{"first_name":"Nils","full_name":"Kretzschmar, Nils","id":"15387","last_name":"Kretzschmar"},{"full_name":"Schöppner, Volker","id":"20530","last_name":"Schöppner","first_name":"Volker"}],"date_created":"2021-09-07T10:31:48Z","title":"Simulating Tightly Intermeshing, Co-Rotating Twin Screw Extruders with SIGMA","year":"2010","place":"San Diego, CA, USA","citation":{"apa":"Kretzschmar, N., &#38; Schöppner, V.

With increasing storage demands and emerging storage services the question how to schedule storage jobs becomes more and more interesting. Since such scheduling problems are often in the class NP-complete an exact computation is not feasible in practice. On the other hand an approximation to the optimal solution can easily be found by means of using heuristics. The problem with this attempt is that the suggested solution may not be exactly optimal and is thus less satisfying. Considering the two above mentioned solution approaches one can clearly find a trade-off between the optimality of the solution and the efficiency to get to a solution at all. This work proposes to apply and combine heuristics in optimization to gain from both of their benefits while reducing the problematic aspects. Following this method it is assumed to get closer to the optimal solution in a shorter time compared to a full optimization.","lang":"eng"}],"file":[{"file_name":"s1-ln7055316-1881058806-1939656818Hwf-1884822883IdV-5442784107055316PDF_HI0001.pdf","access_level":"open_access","file_id":"6188","file_size":171336,"date_created":"2018-12-11T15:21:06Z","creator":"hsiemes","date_updated":"2018-12-13T15:19:40Z","relation":"main_file","content_type":"application/pdf"}],"status":"public","type":"conference","publication":"18th European Conference on Information Systems (ECIS 2010)","ddc":["000"],"keyword":["Decision Support System","Algorithms","Optimization","Market Engineering"],"extern":"1","language":[{"iso":"eng"}],"file_date_updated":"2018-12-13T15:19:40Z","_id":"5685","user_id":"61579","department":[{"_id":"277"}]},{"series_title":"PPSN’10","user_id":"15504","department":[{"_id":"34"},{"_id":"819"}],"_id":"46405","language":[{"iso":"eng"}],"keyword":["benchmarking","multidimensional scaling","consensus ranking","evolutionary optimization","BBOB test set"],"type":"conference","publication":"Proceedings of the 11th International Conference on Parallel Problem Solving from Nature: Part I","status":"public","abstract":[{"lang":"eng","text":"We present methods to answer two basic questions that arise when benchmarking optimization algorithms.

In this paper we propose a novel adaptation algorithm for a filter-and-sum beamformer to adjust the coefficients of FIR filters to changing acoustic room impulses, e.g. due to speaker movement. A deterministic and a stochastic gradient ascent algorithm are derived from a constrained optimization problem, which iteratively estimates the eigenvector corresponding to the largest eigenvalue of the cross power spectral density of the microphone signals. The method does not require an explicit estimation of the speaker location. The experimental results show fast adaptation and excellent robustness of the proposed algorithm.","lang":"eng"}],"status":"public","type":"conference","publication":"IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP 2005)","keyword":["acoustic filter-and-sum beamforming","acoustic room impulses","acoustic signal processing","adaptive principal component analysis","adaptive signal processing","architectural acoustics","constrained optimization problem","cross power spectral density","deterministic algorithm","deterministic algorithms","distant-talking environments","eigenvalues and eigenfunctions","eigenvector","enhanced signal","filter-and-sum beamformer","FIR filter coefficients","FIR filter coefficients","FIR filters","gradient methods","human-machine interfaces","iterative estimation","iterative methods","largest eigenvalue","microphone signals","multichannel signal processing","optimisation","principal component analysis","spectral analysis","stochastic gradient ascent algorithm","stochastic processes"],"language":[{"iso":"eng"}],"_id":"11930","user_id":"44006","department":[{"_id":"54"}]},{"publication":"Proceedings of the Design 2004","type":"conference","status":"public","_id":"39078","department":[{"_id":"672"}],"user_id":"5786","keyword":["mechatronic systems","self-optimization","virtual prototyping"],"language":[{"iso":"eng"}],"year":"2004","place":"Dubrovnik","citation":{"ama":"Gausemeier J, Müller W, Paelke V, Bauch J, Shen Q, Radkowski R.
