Both protocols build on an overlay, which induces an aggregation tree on which heap operations are aggregated in batches, ensuring that our protocols scale even for a high rate of incoming requests. As part of SEAP we provide a novel distributed protocol for the k-selection problem that runs in time O(log n) w.h.p. SKEAP guarantees sequential consistency for its heap operations, while SEAP guarantees serializability. SKEAP and SEAP provide logarithmic runtimes w.h.p. on all their operations. \r\nSKEAP and SEAP provide logarithmic runtimes w.h.p. on all their operations with SEAP having to use only O(log n) bit messages.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1145/3323165.3323193","date_updated":"2022-01-06T07:03:56Z","project":[{"name":"SFB 901","_id":"1"},{"_id":"2","name":"SFB 901 - Project Area A"},{"name":"SFB 901 - Subproject A1","_id":"5"}],"department":[{"_id":"79"}],"title":"Skeap & Seap: Scalable Distributed Priority Queues for Constant and Arbitrary Priorities","external_id":{"arxiv":["1805.03472"]}},{"doi":"10.1145/3323165.3323195","date_updated":"2022-01-06T07:04:04Z","language":[{"iso":"eng"}],"title":"Distributed Computation in Node-Capacitated Networks","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area A","_id":"2"},{"_id":"5","name":"SFB 901 - Subproject A1"}],"department":[{"_id":"79"}],"_id":"8871","type":"conference","year":"2019","citation":{"short":"J.

These primitives are local in the sense that each node can apply them based on local knowledge and by affecting only its 1-neighborhood. Although the specific set of primitives we consider makes it possible to transform any (weakly) connected graph into any other (weakly) connected graph consisting of the same nodes, they cannot disconnect the graph or introduce new nodes into the graph, making them ideal in the context of supervised overlay network transformations. We prove that computing a minimum sequence of primitive applications (even centralized) for arbitrary G_s and G_t is NP-hard, which we conjecture to hold for any set of local graph transformation primitives satisfying the aforementioned properties. On the other hand, we show that this problem admits a polynomial time algorithm with a constant approximation ratio.","lang":"eng"}],"user_id":"477","ddc":["004"],"file":[{"file_id":"12955","creator":"ups","file_size":537649,"success":1,"relation":"main_file","content_type":"application/pdf","date_updated":"2019-08-26T09:21:27Z","date_created":"2019-08-26T09:21:27Z","file_name":"LIPIcs-ICALP-2019-150.pdf","access_level":"closed"}],"file_date_updated":"2019-08-26T09:21:27Z","keyword":["Graphs transformations","NP-hardness","approximation algorithms"],"publication":"Proceedings of the 46th International Colloquium on Automata, Languages, and Programming","publisher":"Dagstuhl Publishing","author":[{"full_name":"Scheideler, Christian","first_name":"Christian","id":"20792","last_name":"Scheideler"},{"id":"11108","last_name":"Setzer","full_name":"Setzer, Alexander","first_name":"Alexander"}],"date_created":"2019-07-08T17:19:01Z","has_accepted_license":"1","status":"public","volume":132,"date_updated":"2022-01-06T06:50:45Z","doi":"10.4230/LIPICS.ICALP.2019.150","series_title":"LIPIcs","language":[{"iso":"eng"}],"title":"On the Complexity of Local Graph Transformations","department":[{"_id":"79"}],"project":[{"_id":"1","name":"SFB 901"},{"_id":"5","name":"SFB 901 - Subproject A1"},{"_id":"2","name":"SFB 901 - Project Area A"}],"publication_status":"published"},{"_id":"12944","date_updated":"2022-01-06T06:51:27Z","doi":"10.1007/978-3-030-24922-9_18","year":"2019","type":"conference","citation":{"apa":"Götte, T., Hinnenthal, K., & Scheideler, C.
