The VCLA was funded by TU Wien for its first four-year period and will continue to be funded for another four years in association with the Doctoral College Logical Methods in Computer Science (LogiCS). 5 In Memoriam VCLA co-chair Helmut Veith (1971- 2016) passed away in tragic circum- stances on March 12, 2016. Accompanying the rebirth of the Aus- trian logic scene his marking of the field, space, and time is further on aug- mented by the students who he men- tored, and by his visionary activities of building bridges between the comput- er science expert and the layman. Helmut studied Computational Log- ic at TU Wien, a studium irregulare with a curriculum he designed him- self, together with Richard Zach.

The local board is responsible for day-to-day management and consults with the advisory board about strategic decisions. The following is the organisational structure from the 2016/2017 reporting period. Since January 2018 the VCLA board has a new structure which is presented at the end of this report.

ALGO 2017 hos- ted by the Algorithms and Complexity Group at TU Wien in September 2017, attracted more than 320 participants. ALGO 2017 combined the following six conferences and workshops: ALGO 2017 volunteers • the European Symposium on Algo- • the Workshop on Algorithmic rithms (ESA) Approaches for Transportation Mo- • the International Symposium on deling Optimization, and Systems Parameterized and Exact Computa- (ATMOS) tion (IPEC) • the International Workshop on • the Workshop on Approximation Algorithmic Aspects of Cloud Compu- and Online Algorithms (WAOA) ting (ALGOCLOUD) • the International Symposium on ALGO 2017 hosted also the Parameteri- Algorithms and Experiments for Wi- zed Complexity Summer School (PCSS), reless Networks (ALGOSENSORS) with a record number of more than 100 participating talents. The congress was opened by the rector of the TU Wien, Sabine Seidler. The scientific program comprised of over 165 paper presentations, tutorials, the ESA test of time award, the PACE competition awards, the Nerode prize award, and several best paper awards. Alongside the scientific part of the Rector of the TU Wien, Sabine Seidler ALGO 2017 program, the social events 8 Activities offered participants a wide range of (NHM).
