For the traveling salesperson problem (TSP) a plethora of features have been suggested. Most of these features are, if at all, only normalized imprecisely raising the issue of feature values being strongly affected by the instance size. Such artifacts may have detrimental effects on algorithm selection models. We propose a normalization for two feature groups which stood out in multiple AS studies on the TSP: (a) features based on a minimum spanning tree (MST) and (b) nearest neighbor relationships of the input instance. To this end we theoretically derive minimum and maximum values for properties of MSTs and k-nearest neighbor graphs (NNG) of Euclidean graphs. We analyze the differences in feature space between normalized versions of these features and their unnormalized counterparts. Our empirical investigations on various TSP benchmark sets point out that the feature scaling succeeds in eliminating the effect of the instance size. A proof-of-concept AS-study shows promising results: models trained with normalized features tend to outperform those trained with the respective vanilla features."}],"date_created":"2023-08-04T07:18:38Z","department":[{"_id":"34"},{"_id":"819"}],"type":"journal_article","keyword":["Feature normalization","Algorithm selection","Traveling salesperson problem"],"publication_identifier":{"issn":["0304-3975"]},"author":[{"first_name":"Jonathan","last_name":"Heins","full_name":"Heins, Jonathan"},{"orcid":"0000-0002-4121-4668","first_name":"Jakob","last_name":"Bossek","full_name":"Bossek, Jakob","id":"102979"},{"last_name":"Pohl","first_name":"Janina","full_name":"Pohl, Janina"},{"id":"105520","last_name":"Seiler","first_name":"Moritz","full_name":"Seiler, Moritz"},{"id":"100740","full_name":"Trautmann, Heike","orcid":"0000-0002-9788-8282","first_name":"Heike","last_name":"Trautmann"},{"full_name":"Kerschke, Pascal","first_name":"Pascal","last_name":"Kerschke"}],"year":"2023","title":"A study on the effects of normalized TSP features for automated algorithm selection","status":"public","intvolume":"       940","date_updated":"2024-06-10T11:57:21Z","language":[{"iso":"eng"}],"_id":"46310","page":"123-145","volume":940,"user_id":"15504","doi":"https://doi.org/10.1016/j.tcs.2022.10.019"},{"date_created":"2023-11-14T15:59:01Z","type":"conference","department":[{"_id":"819"}],"publication":"2023 IEEE Symposium Series on Computational Intelligence (SSCI)","citation":{"bibtex":"@inproceedings{Seiler_Rook_Heins_Preuß_Bossek_Trautmann, title={Using Reinforcement Learning for Per-Instance Algorithm Configuration on the TSP}, DOI={<a href=\"https://doi.org/10.1109/SSCI52147.2023.10372008\">10.1109/SSCI52147.2023.10372008</a>}, booktitle={2023 IEEE Symposium Series on Computational Intelligence (SSCI)}, author={Seiler, Moritz and Rook, Jeroen and Heins, Jonathan and Preuß, Oliver Ludger and Bossek, Jakob and Trautmann, Heike}, pages={361–368} }","ama":"Seiler M, Rook J, Heins J, Preuß OL, Bossek J, Trautmann H.

However, the optimal choice of parameters strongly depends on the instance at hand and should thus be calculated on a per-instance basis. We explore the potential of Per-Instance Algorithm Configuration (PIAC) by using Reinforcement Learning (RL). To this end, we propose a novel PIAC approach that is based on deep neural networks. We apply it to predict configurations for the Lin\\textendash Kernighan heuristic (LKH) for the Traveling Salesperson Problem (TSP) individually for every single instance. To train our PIAC approach, we create a large set of 100000 TSP instances with 2000 nodes each \\textemdash currently the largest benchmark set to the best of our knowledge.

At the same time, we aim at organizing\r\nmarkets whose participants maintain a lively market of services through\r\nappropriate entrepreneurial actions.“\r\nOver the last 12 years, we have developed methods and techniques to\r\naddress problems critical to the convenient, efficient, and secure use of\r\non-the-fly computing. Among other things, we have made the description\r\nof services more convenient by allowing natural language input,\r\nincreased the quality of configured services through (natural language)\r\ninteraction and more efficient configuration processes and analysis\r\nprocedures, made the quality of (the products of) providers in the\r\nmarketplace transparent through reputation systems, and increased the\r\nresource efficiency of execution through reconfigurable heterogeneous\r\ncomputing nodes and an integrated treatment of service description and\r\nconfiguration. We have also developed network infrastructures that have\r\na high degree of adaptivity, scalability, efficiency, and reliability, and\r\nprovide cryptographic guarantees of anonymity and security for market\r\nparticipants and their products and services.\r\nTo demonstrate the pervasiveness of the OTF computing approach, we\r\nhave implemented a proof-of-concept for OTF computing that can run\r\ntypical scenarios of an OTF market. We illustrated the approach using\r\na cutting-edge application scenario – automated machine learning (AutoML).\r\nFinally, we have been pushing our work for the perpetuation of\r\nOn-The-Fly Computing beyond the SFB and sharing the expertise gained\r\nin the SFB in events with industry partners as well as transfer projects.\r\nThis work required a broad spectrum of expertise. Computer scientists\r\nand economists with research interests such as computer networks and\r\ndistributed algorithms, security and cryptography, software engineering\r\nand verification, configuration and machine learning, computer engineering\r\nand HPC, microeconomics and game theory, business informatics\r\nand management have successfully collaborated here.","lang":"eng"}],"series_title":"Verlagsschriftenreihe des Heinz Nixdorf Instituts","language":[{"iso":"eng"}],"alternative_title":["Collaborative Research Centre 901 (2011 – 2023)"],"doi":"10.17619/UNIPB/1-1797","author":[{"last_name":"Haake","first_name":"Claus-Jochen","full_name":"Haake, Claus-Jochen","id":"20801"},{"full_name":"Meyer auf der Heide, Friedhelm","first_name":"Friedhelm","last_name":"Meyer auf der Heide","id":"15523"},{"last_name":"Platzner","first_name":"Marco","full_name":"Platzner, Marco","id":"398"},{"id":"3900","full_name":"Wachsmuth, Henning","last_name":"Wachsmuth","first_name":"Henning"},{"id":"573","full_name":"Wehrheim, Heike","first_name":"Heike","last_name":"Wehrheim"}],"publication_identifier":{"unknown":["978-3-947647-31-6"]},"title":"On-The-Fly Computing -- Individualized IT-services in dynamic markets","year":"2023","intvolume":"       412","date_updated":"2024-07-12T12:07:59Z"},{"oa":"1","project":[{"name":"PhoQC: PhoQC: Photonisches Quantencomputing","grant_number":"PROFILNRW-2020-067","_id":"266"},{"_id":"167","grant_number":"231447078","name":"TRR 142 - B06: TRR 142 - Ultraschnelle kohärente opto-elektronische Kontrolle eines photonischen Quantensystems (B06*)"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"file_date_updated":"2023-12-21T09:34:17Z","citation":{"mla":"Farheen, Henna, et al. “Optimized, Highly Efficient Silicon Antennas for Optical Phased Arrays.” <i>Photonics and Nanostructures - Fundamentals and Applications</i>, vol. 58, Elsevier BV, 2023, p. 101207, doi:<a href=\"https://doi.org/10.1016/j.photonics.2023.101207\">10.1016/j.photonics.2023.101207</a>.","ama":"Farheen H, Strauch A, Scheytt JC, Myroshnychenko V, Förstner J.

This facilitates a dynamic control of light in a compact form factor that enables the synthesis of arbitrary complex wavefronts in the infrared spectrum. We numerically demonstrate a large-scale two-dimensional silicon-based optical phased array (OPA) composed of nanoantennas with circular gratings that are balanced in power and aligned in phase, required for producing elegant radiation patterns in the far-field. For a wavelength of 1.55 μm, we optimize two antennas for the OPA exhibiting an upward radiation efficiency as high as 90%, with almost 6.8% of optical power concentrated in the field of view. Additionally, we believe that the proposed OPAs can be easily fabricated and would have the ability to generate complex holographic images, rendering them an attractive candidate for a wide range of applications like LiDAR sensors, optical trapping, optogenetic stimulation, and augmented-reality displays."}],"publication":"Photonics and Nanostructures - Fundamentals and Applications","doi":"10.1016/j.photonics.2023.101207","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2024-07-22T07:44:33Z","intvolume":"        58","title":"Optimized, Highly Efficient Silicon Antennas for Optical Phased Arrays","year":"2023","publication_identifier":{"issn":["1569-4410"]},"author":[{"id":"53444","first_name":"Henna","last_name":"Farheen","orcid":"0000-0001-7730-3489","full_name":"Farheen, Henna"},{"last_name":"Strauch","first_name":"Andreas","full_name":"Strauch, Andreas"},{"first_name":"J.
