Question on Submission Rules

[gpauusa]

I wanted to ask you few questions on the submission rules:

1/ From the challenge web site it appears to us that the challenge has 4 different categories each ranked separately.
—> navigation in a static environment (based on vision)
—> navigation in a dynamic environment (based on vision)
—> navigation in a static environment (based explicit obstacle information)
—> navigation in a dynamic environment (based explicit obstacle information)

Is this interpretation correct?

2/ Reading the challenge web-site we are unable to understand if there is limit to the number of submissions a single team. Can a team submit several different user_code.py for each race category?

2/ What shall we specify in the submission (i.e. Team members, Institution, …)?

3/ In the challenge the difficulty will be presented in an increasing/decreasing/or random way?

Thanks
Best Regards
Giovanni.
