On page 6 of the whitepaper, the text defines depth and height as follows (bolding mine):
• height, as the length of the longest oriented path to the genesis;• depth, as the length of the longest reverse-oriented path to some tip.
And then describes node D as having "height 2 and depth 2". However, the longest oriented path to the genesis from D (D -> F -> G -> Genesis) appears to be 3. Therefore, wouldn't it be accurate to say D has height 3?
Along the same lines, I have a question about depth. The text says:
G has height 1 and depth 3 (because of the reverse path F, B, A)
But again, if we are looking for the longest path to some tip, then why wouldn't the depth be 4 (F, D, B, A)?
Hey Adam. Welcome to IOTA!
The best place to get answers to these questions is the #tanglemath channel on Slack.
You may also find these threads interesting (not directly related to your question):
You are reading v0.6 from April 3, 2016.Newest one is v1.2 from August 22, 2017.
As @phx said, you can find the latest versions of the whitepaper on #tanglemath of the Slack.
After reading it very quickly, it seems you're right and it has been patched
Ah, okay! I would suggest that the latest version of the whitepaper be made available on the website (www.iota.org) in addition to Slack (the link at the bottom of the page under "Developers" still links to the old 0.6 version). I'd wager that most people seeking information about iota will look first on the official website before thinking to check Slack.
I totally agree.From what I've read on slack they're waiting v2.0 to avoid confusing people.
