Won the First Place at ACM SIGSPATIAL Cup 2019!

The authors of "Distance-Aware Competitive Spatiotemporal Searching Using Spatiotemporal Resource Matrix Factorization" won the first place ($500) at ACM SIGSPATIAL Cup 2019

Dr. Bo Xu, a contest co-chair and a Principal Research Engineer at HERE Technologies, introduced this year challenge in the Contest Session. ACM SIGSPATIAL Cup 2019 was about optimization of agents’ maneuvers based on the ride-hailing simulation provided by the contest organizers. The main challenge was how smartly the agents (or drivers) seeking customers relocate their cars without any communication with other agents while globally minimizing search time of all agents and wait time of all customers. The results of the top three teams (George Mason University, Ludwig-Maximilians-Universität, Eindhoven University of Technology) were very close to each other. I believe tuning parameters to higher the chance to win was the secret. The certificate was awarded at the banquet on November 7, 2019.
