Can someone explain this? http://puu.sh/4LNE6.png [Broken]
What is the relevance of t1 < t2 < t3
t1<t2<t3 just makes sure your time-ordering is right, so you first have v1, afterwards v2, and then v3, and not some other order.
Oh I was thinking of them each representing time intervals for some reason, I get it. Thanks
Separate names with a comma.
