TRWBWCale: yeah, that's waht i mean to say
CaleThis is the same as doing just one tensor contraction.
TRWBWCale: sure.
Cale: i just wanted to make sure the term made the same thing, clearly it's identical usage.
Cale: just like taking some function f(x,y):R^2->R and construction g:R->(R->R) such that (g(x))(y)=f(x,y)
Caleright
_llll_c(A,C(B,C)) ~ c(BxA,C) :)
oops, bad notation
CaleHom(A, Hom(B,C)) ~ Hom(AxB,C)
TRWBW_llll_: actually i did some research in currying in non-functional languages, basic blocks, registers, pointers, etc. got a paper out of it. ;)
_llll_you should write Hom(B,C) different to the outer one. i like HOM(B,C) for the internal one
or B^C, possibly
CaleC^B
_llll_that too
at some point i decided it should be BxA instead, but i forget why now
something to do with bundles
Seebcould anybody tell number of combinations for picking a straight flush poker hand (including ace on top)? I know it's 4*10, but that's not explanatory
TRWBWSeeb: well break it down
Seeb: first pick the suit
Seeb: well you know one card, the ace
Seeb: how many ways can you pick the ret
Seeb: multiply
Seeb: misread that, but that still holds
Seeb: first pick suit, then pick top card
SeebTRWBW: yeah
TRWBW: C(4,1)*...
TRWBWSeeb: only special case you might be confusing is 5,4,3,2,ace
Seeb: or ace,k,q,j
10
SeebI don't get how you get 4*10
TRWBWSeeb: make sense? for this problem ace can be both 1 or 14, so it's like you had 14 cards
Seeb(which is the answer)
TRWBWSeeb: how many different top cards can you have?
Seeb: that is how many cards can be the top card in a straight?
(ignoring suit, let's assume they are all clubs)
Seeb5 to ace <=> 10 different top cards
TRWBWk, so where you missing it?
that is, yes, why aren't you happy with that?
SeebC(4,1)*10 = 4*10, but uhm, doesn't feel like I picked 5 cards
TRWBWSeeb: you didn't. you picked one card actually
