I have a doubt about parity game question in the question paper. In exercise we have given a question we will find the highest value and %2 for Attr i and i-1 for the next one. Is that whole process counted as one Game or else how we are calculating Each game?

Secondly, What is meant by source in the question paper?

And in each game we will assume all the states are still there, and what will be the Qh of the Attr formula in corresponding games?

When we are supposed to halt the games?

Thanks in advance.
