The Abcs of Petri Net Reachability Relaxations
The ABCs of Petri net reachability relaxations Michael Blondin, Universite´ de Sherbrooke, Canada Petri nets form a widespread model of concurrency well suited for the verification of systems with infinitely many configurations. Deciding configuration reachability in Petri nets, which plays a central role in their formal analysis, suffers from a nonelementary time complexity lower bound. We survey relaxations that alleviate this tremendous complexity, both for classical Petri nets and for extensions with affine transformations, branching rules and colored tokens. 1. INTRODUCTION Petri nets are a widespread formalism to model and analyze concurrent systems with possibly infinite configuration spaces over nonnegative counters, i.e. Nk. They offer a great tradeoff between graphical modeling and amenability to algorithmic analysis. In particular, they find applications ranging from program verification (e.g. [German and Sistla 1992; Kaiser et al. 2014; Atig et al. 2011; Delzanno et al. 2002]) to the for- mal analysis of chemical, biological and business processes (e.g. [Esparza et al. 2017; Heiner et al. 2008; van der Aalst 1998]). One of the central questions in Petri net the- ory consists in determining whether a given target configuration, typically an error of a system, is reachable from an initial configuration. This reachability problem, which we will shortly define formally, has been extensively studied over several decades. For a long time, the computational complexity of the problem lay between EXPSPACE- hardness [Lipton 1976] and decidability [Mayr 1981; Kosaraju 1982; Lambert 1992; Leroux 2012]. However, it was recently narrowed down between TOWER-hardness [Cz- erwinski´ et al. 2019], i.e. a tower of exponentials, and Ackermaniann time [Leroux and Schmitz 2019]. -

The Changing Shape of the Computing World
Outside the Box — The Changing Shape of the Computing World Steve Cunningham Computer Science California State University Stanislaus Turlock, CA 95382 [email protected] http://www.cs.csustan.edu/~rsc Something happened to computing while many of us were busy practicing or teaching our craft, and computing is not quite the same thing we learned. We can ignore this change and others will take our place and teach about it, but they will not have the context and the skill to understand the technology behind it and to carry it forward to the success it should have. And if others carry that torch, computer science will be stunted because we didn't recognize and respond to the opportunity. What happened? Simply this—that Xerox and Apple and, yes, Microsoft opened up the box labeled “CAUTION: Computer Inside” and let the user into the computing picture. Users responded hesitantly but increasingly eagerly and now expect the computer to work for them instead of their working for the computer. Every application now in wide use, and any system that supports a general market, has evolved to meet that expectation. Any computing education that does not pay attention to the user’s role in computing is missing the most vibrant and exciting part of computing today. As it says at the top of this page, you are reading an editorial, not an academic paper. As an editorial, this note represents my personal passion and commitment to the user communication part of computing that the “official” computing establishment has long discounted, and I appreciate John Impagliazzo’s offer of this forum to make my case that computer science is missing the boat in not understanding the need to reshape computer science education to fill this void. -

ACM has a core constituency with an interest in Logic and Computation (L&C), witnessed by 1 The many Turing Awards for work centrally in L&C 2 The ACM journal Transactions on Computational Logic 3 Several long-running conferences like LICS, CADE, CAV, ICLP, RTA, CSL, TACAS, and MFPS, and super-conferences like FLoC and ETAPS SIGLOG explores the connections between logic and computing covering theory, semantics, analysis, and synthesis. SIGLOG delivers value to its membership through the coordination of conferences, journals, newsletters, awards, and educational programs. SIGLOG enjoys significant synergies with several existing SIGs. Natarajan Shankar SIGLOG 2/9 Logic and Computation: Early Foundations Logicians like Alonzo Church, Kurt G¨odel, Alan Turing, John von Neumann, and Stephen Kleene have played a pioneering role in laying the foundation of computing.

Detecting Anomalous Citation Groups in Journal Networks Sadamori Kojaku1, Giacomo Livan2,3 & Naoki Masuda4,5,6*
www.nature.com/scientificreports OPEN Detecting anomalous citation groups in journal networks Sadamori Kojaku1, Giacomo Livan2,3 & Naoki Masuda4,5,6* The ever-increasing competitiveness in the academic publishing market incentivizes journal editors to pursue higher impact factors. This translates into journals becoming more selective, and, ultimately, into higher publication standards. However, the fxation on higher impact factors leads some journals to artifcially boost impact factors through the coordinated efort of a “citation cartel” of journals. “Citation cartel” behavior has become increasingly common in recent years, with several instances being reported. Here, we propose an algorithm—named CIDRE—to detect anomalous groups of journals that exchange citations at excessively high rates when compared against a null model that accounts for scientifc communities and journal size. CIDRE detects more than half of the journals suspended from Journal Citation Reports due to anomalous citation behavior in the year of suspension or in advance. Furthermore, CIDRE detects many new anomalous groups, where the impact factors of the member journals are lifted substantially higher by the citations from other member journals. We describe a number of such examples in detail and discuss the implications of our fndings with regard to the current academic climate. Te volume of published research is growing at exponential rates 1, creating a pressing need to devise fast and fair methods to evaluate research outputs. Measuring academic impact is a controversial and challenging task2. Yet, the evaluation of research has increasingly been operationalized in terms of the citations received by research papers and citation-based bibliometric indicators, such as the h-index and the journal impact factor (JIF), which are widely used to evaluate individual researchers, academic institutions, and the research output of entire nations3–6. -

Gold Route Open Access Journals in Engineering and Technology: Analysis of Research Impact and Implications for Scholarly Communication
Gold Route Open Access Journals in Engineering and Technology: Analysis of Research Impact and Implications for Scholarly Communication Ifeanyi J. Ezema, Ph.D Research Fellow Department of Information Science University of South Africa Nnamdi Azikiwe Library University of Nigeria Nsukka [email protected] Abstract This study examines the research impact of gold open access (OA) journals in engineering and technology. A total of 37 gold route journals that request article processing charges (APC) and 66 other OA journals without APC (i.e., platinum OA) in the field were found in the Directory of Open Access Journals and used for the study. The publishers, APC charges, and the year each journal was added to DOAJ were identified and included in this study. An informetric approach was used to extract research impact indicators (citations, paper productivity, cite/paper, cite/journal, and h-index) of journals. Findings revealed that the publishers of the APC journals were dominated by commercial publishing companies, producing over 60% of the journals. Article processing charges ranged from $7.60 to $3,471.50, with an average of $727.00. Gold route open access (APC) journals performed better than open access non-APC OA journals, since they produced 51.2% of the papers, 71.8% of the total citations, and 65.1% of the total h- index. There was a weak positive correlation between the APC amount of the gold route journals and their research impact. Introduction The past one and a half decades has witnessed a revolution in scholarly communication with the emergence of open access publishing.
