From November 2015 till October 2017, I was a postdoc on the LSV Cachan, funded by a fellowship of the DAAD (German Academic Exchange Service), hosted by Philippe Schnoebelen, and the venture VERICONISS by Stefan Göller. Since November 2018, I’m a tenure-track school member at the Max Planck Institute for Software Systems (MPI-SWS) in Kaiserslautern, the place I head the Models of Computation group. Until December 2010, I studied Computer Science (with a minor in Mathematics) at Universität Hamburg. Before that, I obtained a PhD with Prof. Roland Meyer within the Concurrency Theory Group in Kaiserslautern. More particularly, I am excited about decidability and complexity issues of infinite-state techniques. I defended my dissertation on June nineteenth, 2015. My analysis is anxious with theoretical foundations of verification and synthesis of software methods. From November 2017 until October 2018, I used to be a postdoc at IRIF, Université Paris-Diderot, funded by a fellowship of the Fondation Sciences Mathématiques de Paris and hosted by Olivier Serre.
As well as, I’m engaged on choice problems for infinite teams, where I search to apply methods from verification and achieve insights on how to plan infinite-state fashions with nice analysis properties. Thanks lots to everybody who gave me advice on the applying! Lin, I’m organizing the Theorietag 2023 on automata and formal languages. RP 2022 will probably be in Kaiserslautern, please submit! EAPLS Best Paper Award at ETAPS 2021. News – Along with Anthony W. – Distinguished Paper Award at POPL 2021. EATCS Distinguished Dissertation Award (see my thesis). We research the issue of deciding whether or not a given language is directed. Best Student Paper Award at ICALP 2015 (Track B). My project FINABIS, Finite-state abstractions of infinite-state programs, will likely be funded by an ERC Starting Grant. Deciding directedness is a fundamental problem in connection with ultimate decompositions of downward closed sets. One current focus is synthesis of finite-state abstractions of infinite-state techniques (separability problems, downward closures, Parikh photos), which can be utilized as correctness certificates or as constructing blocks for choice procedures.
Will I be guaranteed to assessment if I volunteer? Is that this open peer review? Volunteering isn’t a assure that you may be requested to evaluation. Additionally, it may very well be that sufficient reviewers have accepted an invitation to evaluation already, through which case we would not invite any extra. However, any reviewer has the choice to signal their report, and as soon as accepted for publication then that review might be proven publicly – once more this is non-obligatory. For one, reviewers must have relevant skills for any manuscript and void of any conflicts of curiosity. No, peer review remains to be single-blind and all recommendations are non-public between the authors and Academic Editor. Additionally, there may already be sufficient reviewers discovered via different means, for instance, invitations despatched by the academic Editor In-Person Learning in charge. Why aren’t there more manuscripts available? This is for a lot of causes. What are the editorial criteria? You will even be given additional data if invited to evaluation. Manuscripts are shown when authors have opted-in for obtaining reviewers by the reviewer-match service. Please go to the editorial standards page for initial steering.
CONCUR 2018) that it is decidable whether, for 2 given VASS, there exists an everyday separator. Moreover, we provide tight dimension bounds for separators in the case of fixed dimensions and unary/binary encodings of updates and NFA/DFA separators. In particular, we settle the aforementioned question. We examine common separators of vector addition programs (VASS, for short) with coverability semantics. Bounding the number of reversals in a counter machine is one of the vital outstanding restrictions to realize decidability of the reachability drawback. However, they supply a triply exponential higher sure and a doubly exponential decrease bound for the scale of such separators and go away open which certain is tight. We show that if two VASS have disjoint languages, then there exists an everyday separator with at most doubly exponential size. This permits us to determinize (and thus complement) with out the powerset building and avoid one exponential blowup. Actually, they show that a regular separator exists if and provided that the two VASS languages are disjoint.
2mb – 90 days of statistics. You may tweak your logging to keep things smaller if required. Currently (May 2022 edge construct 108) a full install to the /decide folder you really require about 100mb of space. 35mb x2 for the AGH binary and again for when it backups and In-Person Learning upgrades. 53mb – 7 days of question logs. Since 21.02, there’s a official AdGuard Home bundle which will be put in by means of opkg. If you wish to have longer retention intervals for query/statistics information, consider shifting the storage listing to outside your routers flash space. If you’re using the default tmpfs storage, you must set a comparatively brief retention period or disable logging altogether. The opkg package for 21.02 has also been confirmed to work on 19.07, but would require transferring the proper ipk by means of SSH or SCP and putting in with opkg manually on account of not being present within the 19.07 packages repository. Alternatively you may also perform an exroot configuration. One in all the primary advantages of AGH is the detailed query and statistics information supplied, nonetheless for many routers having long retention periods for this knowledge can cause issues (see flash/storage house requirements).
