<0> is nth_element fast?
<1> if it's not, then come back to us.
<1> premature optimisation evil and all that
<0> hmm. problem with nth_element is that it only sorts values.. i need to sort a reference list as well, to find the actual nearest neighbors
<1> how about you use a heap?
<0> oh, there's a functor slot
<1> yes there is
<0> so hard to decide.. the distance matrix seems prohibitively large
<1> just go ahead with it and see
<1> I'm a big fan of storing as much as possible in memory :)
<1> otherwise your option is
<1> when seeing a new element, scan the whole list computing distances, then check the k-nearest-neighbours from those distances
<2> vawjrwrk can u give me some free c++ books , from where i can learn fast and eficient C++?
<1> which is slower
<1> obviously
<1> brb reboot
<2> who can give me some free c++ books
<2> a mean good c++ books
<3> free and good do not mix.
<2> :D
<2> must mix
<2> i'm poor
<4> "thinking in c++" is free, and people say it's moderately good
<2> exception can u give me a link ?
<4> don't have it - but try googling
<2> k
<2> 10x
<4> http://www.cppreference.com/index.html
<4> it's not a proper book, but it seems ok to me
<2> k
<2> thanks a lot
<5> http://www.rudbek.com/books.html
<2> peterhu , free books
<5> those are the books that will make you a good c++ programmer
<5> free or not, they're worth it
<5> get some quid to rub together and just buy them
<5> rob a bank
<5> sell your body
<5> whatever
<2> :D
<5> as for free, exceptions suggestion is the only one i know of
<6> erm, does someone know a good place from where to get photoshop text styles? :)
<7> greetings
<7> I got the Windows profiler you like suggest me yesterday
<7> however, it speaks chinese
<7> and I know no chinese
<7> its called GlowCode
<7> http://www.noidea128.org/sourcefiles/16263.html
<7> so... does this mean anything to you people?
<7> my application is called AcoAcs
<7> otherwise, you can just say no....
<2> and what's your aplication doing?
<7> right before exiting, it pop ups some error
<0> is it safe to do this? "std::set_intersection(A.begin(),A.end(),B.begin(),B.end(),A.begin(),A.end());" ?
<7> Debug ***ertion Failed! Expression: _CrtCheckMemory()
<7> For information on how your program can cause an ***ertion failure, see the Visual C++ documentation on ***erts.
<2> how many time do u spent to do this ?
<2> sorry for my english
<7> what do you mean?
<2> from how long do u wrote that ?
<2> 1 week
<7> I just got the profiler, I am not sure exactly how it works, and what do the output mean...
<7> a few months.... why?
<2> i'm curios , that's all
<2> ;)
<7> so.... how can I spot a memory error?
<7> 1 week for what?
<2> for making that
<7> with, or without the errors?
<2> with all
<7> ok....
<2> do u earn any money for making this ?
<2> programming c++ ?
<7> non
<2> open source ?
<2> :D
<7> its for a project...
<8> McNoosheh spot a "memory error" ?? what is that
<2> k
<2> talk with vawjrwrk it's good on c++
<7> vawjrwrk: I got this: "Debug ***ertion Failed! Expression: _CrtCheckMemory()" before exiting my application
<8> it said more than that
<7> I got a profiler: GlowCode
<8> the error said more than that
<7> but can't 'read' exactly what it says
<7> there is the full error:
<7> ---------------------------
<7> Microsoft Visual C++ Debug Library
<7> ---------------------------
<7> Debug ***ertion Failed!
<7> Program: ...g) ....exe
<7> File: g:\exam scheduling (timetabling) project\acowin v.32 last version before converting to eval, c2, back to acowin\acoacs.cpp
<7> Line: 480
<7> Expression: _CrtCheckMemory()
<7> For information on how your program can cause an ***ertion failure, see the Visual C++ documentation on ***erts.
<7> (Press Retry to debug the application)
<7> ---------------------------
<7> Abort Retry Ignore
<7> ---------------------------
<9> ...
<7> you want me to run it without the ***ertion?
<8> huh??
<7> nevermind....
<8> do you have the file it mentions?
<7> you mean, the .cpp file?
<8> yes
<7> http://www.noidea128.org/sourcefiles/16264.html
<7> its pretty long
<8> I didn't want to see it, I wanted YOU to go look a line 480
<7> maybe an error in 'control' or 'problem' ?
<7> nothing much to see on line 480
<7> does the profiler log help?
<8> I have no idea
<8> well, the error claims the error was detected on line 480 of that file
<7> how can I make use of it?
<7> yes, but I already knows that there is an error over there, I put the ***ert hoping it will make things clearer,,, but it did not
<0> vawjrwrk: is it safe to do this? "std::set_intersection(A.begin(),A.end(),B.begin(),B.end(),A.begin(),A.end());" ?
<7> dextre: we are cnoncentrating on MY problem now
<8> that looks like too many args
<8> McNoosheh YOU don't get to decide
<8> dextre that isn't one of the acceptable signatures
<0> you're right. missed it. but say if i lose that last argument, is the set_intersection performed in place? like, will i get corrupt unpredictable output?
<8> I'd subbest that it's not a good idea, I'd have to check all my refernces
<7> ok
<8> oops
<8> "The destination range should not overlap the source ranges"
<8> McNoosheh we don'[t have "turns" here
<7> a token ring?
<0> thanks varjr
<8> are you SURE that's the file that was compiled into what you're running
<8> line 480 is a comment
<7> L480: _***ERTE( _CrtCheckMemory() );
<7> Which is not telling me anything I don't already know
<7> if you are the expert and you can't find it, does that mean that I can''t hope to get the solution?
<8> that is line 515 in what you posted...or well
<7> ....
<8> McNoosheh are you always this stupid\
<0> lol
<2> 480: problem->IndentationPrint();
<8> it seems that maybe the source isn't what was compiled, but at anyrate
<7> My compiler tells me otherwise...
<8> you've apparently managed to step on memory someplace (wild pointer most likely)
<8> did you write all this code??
<8> or is it a copy/paste from other places
<7> non, not all of it
<7> i didnt start from scratch
<7> there are a lot of dynamic allocations
<2> there are many guys who work on this porject ?
<8> or perhaps one of those delete statments you commented out is causing the leak
<7> here it is: the { <-- curly braces are written on a new line, that's why the differences in the line numbers
