Invitation to contribute and participate

ARCO (Algorithmic Research: Cooperation around Oresound) was established 2011 as a network for exchange of research within algorithms and to promote the general interest in this research area within the Oresund Region. The idea is to meet once or twice per year for a one-day workshop.

On April 12th 2024, at the Royal Danish Academy of Sciences and letters, H.C. Andersens Boulevard 35, Copenhagen Central, we plan to have some talks, some lunch together, more talks, opportunities for collaboration, smørebrød for dinner, and then the possibility of going out for a drink on town in the evening. Workshop attendance including meals is free, and the venue is close to the central station for convenience.
