Scattered walkers in street networks: robust decentralized gatherings

How to meet if we are dispersed in a city? Coordinating, by exchanging our positions thanks to modern means of communication, seems easy. But how to achieve the same result if communications are impossible and no meeting point is identifiable? This is the case, for example, during a repressed social movement. The objective of my thesis is to find the key ingredients for a movement tactic to ensure that walkers will meet in the same place, regardless of their starting positions.

To present my results, I am pleased to invite you to my thesis defense titled Scattered Walkers in Street Networks: Robust Decentralized Gatherings, a more detailed summary of which is provided in the following 3-minute video.
