In lecture 3(at 42mins) Guttag is talking about the number of divisions being roughly 12345/0.01^2=26.897 ????? He also talks about epsilon telling how many divisions exist but not 0.01??? if you ask me epsilon = 0.01(-:

Question

huh?

I woke up thinking about this today. i watched it yesterday and that part just did not make sense to me.
Can anyone explain it? Because if it can predict how many guesses you are going to use it would be helpful.

I'm still waking up and thinking about it, and yes! can anyone help?

One more question. Why is c not striped? 
>>> 'www.example.com'.strip('cmwz.')
'example.co'

go back and start watching at 34:53 or before
36:10 - states the iterations are log base two
37:24 - log base two of the number of values in the search space
40:53 - log base 2 of the size of the search space
42:23 - describes the size of the search space as n divided by epsilon squared
             then pronounces 26.897

at 41:04 he alludes to a previous discussion of the size of the search space but i couldn't find that

perhaps he was leaving some of it for us to figure out or maybe seeing if we were paying attention, he even transposed two of the numbers.

why do you think it is log base two of the size of the search space?

"... One more question. Why is c not striped?  ..."
how does strip work??

anonymous · Answer

It's indeed about log base 2:
>>> math.log(12345/0.01**2,2)
26.879351595579596
