glares in confusion at the (16, 2) value O_o
<egg|laptop|egg>
that's not a "wrong maximum" case, what's going on there
<mlbaker>
bofh: ya
<bofh>
(16, 2)? what the hell
* egg|laptop|egg
pokes NMaximize with a stick

bofh: n=16, m=2 went from 3.96373'42717'29440'50795'67349'30105'71775'89526'50712 to 3.96373'42717'29440'50795'71979'16503'12880'68316'16647
<bofh>
that's a difference, uhh, a lot of decimal places back.
<egg|laptop|egg>
yeah at the 21st decimal place
<egg|laptop|egg>
bofh: (also, that's why you group digits,)
<bofh>
also hälp why am I reading math papers in French

<egg|laptop|egg>
bofh: hmmmmmm changing the precision on one of the bounds of the maximization region changes the value, that's *weird*
<egg|laptop|egg>
maybe i should not use nmaximize

bofh: fuck it i'll find the root of the derivative by telling mathematica to bisect that and then evaluate there

bofh: also apparently bisection is called Method->"Brent"
<egg|laptop|egg_>
bofh: they're good root finders, bront
<egg|laptop|egg_>
wait no the misspelling is actually brent already
<egg|laptop|egg_>
they're good root finders, brent
