Getting started
Apparently, some browsers do not support embedded pdf files. You can download the pdf with more information about the competition here.
There is no limit on the number of participants per team. However, in light of rule 11, each team can submit at most one algorithm. Hence, if you would like to develop multiple algorithms you should participate in the competition via multiple teams, with each person being a member of at most one team.
File format
Yes there is! You can download the document in the format tab. Since some browsers do not seem to support embedded pdf files, you can also directly download it here.
In a phased tournament the games of each time slot in the two halves need NOT necessarily be identical (although this is also not forbidden). As an illustration, the following example is also a phased tournament (consider e.g. time slot s2 and time slot s7):
s1 s2 s3 s4 s5 s6 s7 s8 s9 s10
1-2 2-5 2-4 2-3 6-2 | 3-1 2-1 1-4 6-1 1-5
3-4 4-1 1-6 5-1 4-5 | 5-2 4-3 2-6 5-4 3-6
5-6 5-6 5-3 6-4 1-3 | 4-6 6-5 3-5 3-2 4-2

The more extended RobinX format also provides well-known symmetry structure such as the mirrored tournament structure where also the composition of the rounds between two legs is important, but for simplicity these structures will not be considered in the ITC2021 competition.
