GraphMasters will take place on Thursday June 11, one day after IWOCA. It is an open workshop organized to foster collaboration between researchers interested in graph algorithms and problems. See for the previous editions.

The spirit of the workshop is informal: (virtual) working space is provided to the participants, who are welcome to group as they like and seek each other’s counsel and opinion.

Participants are encouraged to bring interesting problems to share with others. We welcome all graph-related problems, including those not directly involving graphs but that you suspect may be modeled as such. We typically gather some problems beforehand to startup the discussion.

You are warmly invited to suggest a problem beforehand by sending an email to conte [at]
Participants are also encouraged to present their problems at the Open Problems Session held during IWOCA 2020.

A list of open problems from previous editions of IWOCA (not necessarily about graphs) is maintained at
