Theoretical algorithm design for speed scaling problems often tends to discretize problems, as our tools in the discrete realm are often better developed or understood. Using the above speed scaling variant with variable, continuous maximal processor speeds and energy prices as an example, we demonstrate that a more direct approach via tools from variational calculus can not only lead to a very concise and elegant formulation and analysis, but also avoids the “explosion of variables/constraints” that often comes with discretizing. Using well-known tools from calculus of variations, we derive combinatorial optimality characteristics for our continuous problem and provide a quite concise and simple correctness proof.","lang":"eng"}],"doi":"10.1016/j.tcs.2017.03.021","has_accepted_license":"1","title":"Continuous Speed Scaling with Variability: A Simple and Direct Approach","file":[{"date_created":"2018-03-21T13:07:43Z","content_type":"application/pdf","file_id":"1567","access_level":"closed","file_size":494600,"file_name":"110-TCSSubmission.pdf","creator":"florida","success":1,"date_updated":"2018-03-21T13:07:43Z","relation":"main_file"}],"user_id":"477","type":"journal_article","ddc":["040"],"publication":"Theoretical Computer Science","page":"1-13"},{"year":"2017","type":"mastersthesis","status":"public","date_created":"2017-10-17T12:41:14Z","publisher":"Universität Paderborn","date_updated":"2022-01-06T06:51:06Z","_id":"117","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt C1","_id":"13"},{"name":"SFB 901 - Project Area C","_id":"4"}],"supervisor":[{"last_name":"Blömer","id":"23","first_name":"Johannes","full_name":"Blömer, Johannes"}],"title":"Attribute-based Signatures using Structure Preserving Signatures","author":[{"first_name":"Pascal","full_name":"Bemmann, Pascal","id":"32571","last_name":"Bemmann"}],"department":[{"_id":"64"}],"citation":{"ieee":"P.

Current approaches reduce the AutoML problem to optimization of hyperparameters. Based on recursive task networks, in this paper we present one approach from the field of automated planning and one evolutionary optimization approach. Instead of simply parametrizing a given pipeline, this allows for structure optimization of machine learning pipelines, as well.

Techniques, such as interviewing by requirements engineers, are typically applied to identify the user’s needs. We want to partially automate even this first step of requirements elicitation by methods of evolutionary computation. The idea is to enable users to specify their desired software by listing examples of behavioral descriptions. Users initially specify two lists of operation sequences, one with desired behaviors and one with forbidden behaviors. Then, we search for the appropriate formal software specification in the form of a deterministic finite automaton. We solve this problem known as grammatical inference with an active coevolutionary approach following Bongard and Lipson [2]. The coevolutionary process alternates between two phases: (A) additional training data is actively proposed by an evolutionary process and the user is interactively asked to label it; (B) appropriate automata are then evolved to solve this extended grammatical inference problem. Our approach leverages multi-objective evolution in both phases and outperforms the state-of-the-art technique [2] for input alphabet sizes of three and more, which are relevant to our problem domain of requirements specification.","lang":"eng"}],"doi":"10.1145/3071178.3071258","has_accepted_license":"1","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subproject B1","_id":"9"},{"name":"SFB 901 - Project Area B","_id":"3"}],"file":[{"date_created":"2018-11-02T15:00:35Z","content_type":"application/pdf","access_level":"closed","file_id":"5290","file_size":1092021,"file_name":"p1327-wever.pdf","creator":"ups","success":1,"date_updated":"2018-11-02T15:00:35Z","relation":"main_file"}],"title":"Active Coevolutionary Learning of Requirements Specifications from Examples"},{"project":[{"_id":"1","name":"SFB 901"},{"_id":"8","name":"SFB 901 - Subprojekt A4"},{"_id":"2","name":"SFB 901 - Project Area A"}],"has_accepted_license":"1","abstract":[{"text":"Research on ad copy design is well-studied in the context of offline marketing. However, researchers have only recently started to investigate ad copies in the context of paid search, and have not yet explored the potential of information cues to enhance customers’ search process. In this paper we analyze the impact of an information cue on user behavior in ad copies. Contrary to prevalent advice, results suggest that reducing the number of words in an ad is not always beneficial. Users act quite differently (and unexpectedly) in response to an information cue depending on their search phrases. In turn, practitioners could leverage the observed moderating effect of an information cue to enhance paid search success. Furthermore, having detected deviating user behavior in terms of clicks and conversions, we provide first indicative evidence of a self-selection mechanism at play when paid search users respond to differently phrased ad copies.","lang":"eng"}],"title":"Achieving more by saying less?

Yet, research investigating the impact of placing paid search ads on less prominent positions on subsequent consumer behavior is limited to the online environment. This paper presents a field experiment using differences-in-differences analysis to investigate whether the targeting of a less prominent ad position can be beneficial for bricks-and-mortar retailers. Results indicate that paid search advertising budgets could be allocated more efficiently by targeting less prominent ad positions, thus allowing bricks-and-mortar retailers with a limited marketing budget to increase the reach of their marketing campaign, attract more consumers to their website and achieve an overall increase in conversions. Furthermore, the pay-per-click billing mechanism allows advertisers to increase their marketing reach at no additional cost. Consequently, bricks-and-mortar retailers should consider targeting less prominent ad positions to reduce advertising costs while simultaneously enhancing advertising benefits.","lang":"eng"}],"has_accepted_license":"1","citation":{"short":"D.

Architectural knowledge of the existing ecosystems is implicit and fragmented among online documentation. In protection of intellectual property, existing documentation hardly reveals influential business strategies that affect the ecosystem structure. Thus, other platform providers can hardly learn from the existing ecosystems in order to systematically make reasonable design decisions with respect to their business strategies to create their own ecosystems. In this paper, we identify a variability model for architectural design decisions of a store-oriented software ecosystem product line from an enterprise perspective, comprising business, application, and infrastructure views. We derive the variability model from fragmentary material of existing ecosystems and a rigorous literature review using a research method based on the design science paradigm. To show its validity, we describe real-world ecosystems from diverse domains using the variability model. This knowledge helps platform providers to develop customized ecosystems or to recreate existing designs in a systematic way. This, in turn, contributes to an increase in designer and developer productivity."}],"title":"A Variability Model for Store-oriented Software Ecosystems: An Enterprise Perspective","file":[{"file_size":566612,"file_name":"Jaz_ICSOC17.pdf","creator":"bahareh","date_created":"2018-11-12T18:55:55Z","content_type":"application/pdf","access_level":"closed","file_id":"5532","relation":"main_file","date_updated":"2018-11-12T18:55:55Z","success":1}]},{"date_updated":"2022-01-06T06:51:19Z","_id":"125","file_date_updated":"2018-10-31T13:30:13Z","status":"public","language":[{"iso":"eng"}],"publication_identifier":{"isbn":["978-3-319-69083-4"]},"year":"2017","publisher":"Springer, Cham","date_created":"2017-10-17T12:41:16Z","department":[{"_id":"79"}],"publication_status":"published","citation":{"apa":"Feldmann, M., &#38; Scheideler, C.

Additionally, recent literature reports that online ratings in peer-to-peer markets tend to be inflated overall, undermining the reliability of online ratings as a quality signal. This study proposes a two-period model for optimal price setting that takes (potentially inflated) ratings into account. Our theoretical findings suggest that sellers in the medium-quality segment have an incentive to lower first-period prices to monetize on increased second-period ratings and that the possibility on monetizing on second-period ratings depends on the reliability of the rating system. Additionally, we find that total profits and prices increase with online ratings and additional quality signals. Empirically, conducting Difference-in-Difference regressions on a comprehensive panel data set from Airbnb, we can validate that price increases lead to lower ratings, and we find empirical support for the prediction that additional quality signals increase prices. Our work comes with substantial implications for sellers in peer-to-peer markets looking for an optimal price setting strategy. Moreover, we argue that our theoretical finding on the weights between online ratings and additional quality signals translates to conventional online markets."}],"project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt A4","_id":"8"},{"name":"SFB 901 - Project Area A","_id":"2"}],"author":[{"last_name":"Neumann","id":"32456","full_name":"Neumann, Jürgen","first_name":"Jürgen"},{"first_name":"Dominik","full_name":"Gutt, Dominik","id":"14368","last_name":"Gutt"}],"file":[{"date_updated":"2018-11-12T09:57:18Z","relation":"main_file","success":1,"creator":"d0mi","file_name":"A HOMEOWNER_S GUIDE TO AIRBNB_ THEORY AND EMPIRICAL EVIDENCE FOR.pdf","file_size":595270,"file_id":"5476","access_level":"closed","content_type":"application/pdf","date_created":"2018-11-12T09:57:18Z"}],"conference":{"name":"25th Conference on Information Systems (ECIS)","location":"Guimaraes, Portugal"},"title":"A Homeowner’s Guide to Airbnb: Theory and Empirical Evidence for Optimal Pricing Conditional on Online Ratings"},{"project":[{"name":"SFB 901","_id":"1"},{"_id":"9","name":"SFB 901 - Subprojekt B1"},{"_id":"3","name":"SFB 901 - Project Area B"}],"author":[{"last_name":"Sergio Djoum Temdjim","full_name":"Sergio Djoum Temdjim, Albin","first_name":"Albin"}],"title":"Evaluation of Software Reputation Matching Based on App Reviews","user_id":"477","citation":{"ama":"Sergio Djoum Temdjim A. <i>Evaluation of Software Reputation Matching Based on App Reviews</i>.
