Since the practice round doesn't seem to provide a scoreboard, I'd like to open this thread to discuss scores and possible approaches for the problem. We got the following scores after some ideas:
A: 2 B: 5 C: 5 D: 1802 E: 2083 Total: 3897
We also tryied to calculate an upper bound for some of the tasks: D upper bound: 1900 E upper bound: 2804 (probably can be significantly improved)
I will post my ideas in the comments. Did anyone managed to get a better sccore? or had an insight to the problem?
