    Abstract Am 4./5. Mai 2020 fand der 10. KIM Workshop statt. Durch die COVID-19-Pandemie konnte die Veranstaltung nicht wie gewohnt in Mannheim abgehalten werden, sondern wurde kurzerhand in eine Online-Veranstaltung umgewandelt. Im Folgenden möchten wir auf einige organisatorische Punkte dieser Online-Veranstaltung eingehen und unsere Erfahrungen dabei für andere Online-Veranstalter teilen. Zudem haben wir gegen Ende des Online-Workshops auch einige Fragen an die TeilnehmerInnen gestellt, welche hier zusammen mit den Antworten integriert werden.

  6. Book ; Online: Unsatisfiable CNF Formulas need many Conflicts

    Scheder, Dominik / Zumstein, Philipp

    Abstract A pair of clauses in a CNF formula constitutes a conflict if there is a variable that occurs positively in one clause and negatively in the other. A CNF formula without any conflicts is satisfiable. The Lovasz Local Lemma implies that a k-CNF formula is satisfiable if each clause conflicts with at most 2^k/e-1 clauses. It does not, however, give any good bound on how many conflicts an unsatisfiable formula has globally. We show here that every unsatisfiable k-CNF formula requires 2.69^k conflicts and there exist unsatisfiable k-CNF formulas with 3.51^k conflicts.

    Comment: new version; added an upper bound on the number of conflicts

    Abstract Reproducible research and open science practices have the potential to accelerate scientific progress by allowing others to reuse research outputs, and by promoting rigorous research that is more likely to yield trustworthy results. However, these practices are uncommon in many fields, so there is a clear need for training that helps and encourages researchers to integrate reproducible research and open science practices into their daily work. Here, we outline eleven strategies for making training in these practices the norm at research institutions. The strategies, which emerged from a virtual brainstorming event organized in collaboration with the German Reproducibility Network, are concentrated in three areas: (i) adapting research assessment criteria and program requirements; (ii) training; (iii) building communities. We provide a brief overview of each strategy, offer tips for implementation, and provide links to resources. We also highlight the importance of allocating resources and monitoring impact. Our goal is to encourage researchers - in their roles as scientists, supervisors, mentors, instructors, and members of curriculum, hiring or evaluation committees - to think creatively about the many ways they can promote reproducible research and open science practices in their institutions.

    Abstract A neat 1972 result of Pohl asserts that [3n/2]-2 comparisons are sufficient, and also necessary in the worst case, for finding both the minimum and the maximum of an n-element totally ordered set. The set is accessed via an oracle for pairwise comparisons. More recently, the problem has been studied in the context of the Renyi-Ulam liar games, where the oracle may give up to k false answers. For large k, an upper bound due to Aigner shows that (k+O(\sqrt{k}))n comparisons suffice. We improve on this by providing an algorithm with at most (k+1+C)n+O(k^3) comparisons for some constant C. The known lower bounds are of the form (k+1+c_k)n-D, for some constant D, where c_0=0.5, c_1=23/32=0.71875, and c_k=\Omega(2^{-5k/4}) as k goes to infinity.
