Ah. OK....

So at 700 levels and say 10 million nodes, that would mean that each node had an average of 1.023 children? Wow, that's a pretty strung-out hierarchy.

some are worse than others as far as strung out. Most of it depends on the business model employed. I have seen one tree strung out to about 1200 levels but with only 500k nodes.

Binary Trees in the MLM industry.


Heh... I thought binaries were illegal in the U.S. I thought uni-level was the only legal method for an MLM.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

Pyramid schemes are illegal - and matrix, unilevel and binary trees could all be a pyramid scheme. The Fed monitors MLMs closely and makes sure they are in compliance with the law. MLMs and Pyramid schemes are not that much different - just one is legal and the other isn't.

Yep... agreed. And the difference between a pyramid scheme and a legal MLM is a legal MLM actually sells product or tangible services.
