Hey Vasia! Nice work, it looks really cool!
Concerning the problem of figuring out the number of iterations: - In the long run we can save this with the incremental rollout that we are working on - As a temporary workaround, you could store the number of elapsed iterations in a static variable somewhere. You set it from the "open()" or "close()" function of one of the UDFs. The convergence criterion for the delta iterations can pick it up from there (access the static variable). Concerning the edges with / without weights: Can you use a custom data type and have the weight "null" when they are not set/used? Greetings, Stephan
