limit of series

Hi,

I have a series of values which seems to converge to some values.
Is it possible to find its limit ?

like limit( series) ?

I can take minimal value here, but maybe is better solution.

TIA

Adam

Re: limit of series

Hello, Adam!

You mean not SERIES, bat SEQUENCE.

The problem is not correct from a mathematical point of view. See the 
mathematical definition of LIMIT.

For a finite sequence a[1],...,a[N] you can compute MAX and MIN, bat not 
LIMIT.

This is a reply from a pure mathematician :-)

From the point of view of physics (or other applied sciences), the 
question is absolutely meaningful. And people do this sort of things 
often.

It would be useful to have some theoretical guesses about how this 
sequence converges to a limit - exponentially, by a power law, or 
something. If, for example, we suppose a power-law convergence, then a 
reasonable procedure is to use the anzatz

x_n = c_0 + c_1/n + c_2/n^2 + ...

and fit the coefficients c_0, c_1, ... to the data (probably, omitting 
an initial part of the sequence where this asymptotics is not yet valid). 
Then c_0 is the limit.

Another often situation is exponential:

x_n = c_0 + c_1 \exp(-a_1 n) + c_2 \exp(-a_2 n) + ...

(for example, x_n is an activity of a sample with several isotopes with 
different life times). Again, fit the data, and you have the limit 
(perhaps, the percentage of uranium, which has nearly infinite life time).

Re: limit of series

Andrey,

in this case the value of the "limit" is highly dependent on the chosen 
approximation

Not highly. Usually, just a little. And an estimate of this dependence is 
usually attached to the result as a "model error" (in addition to 
statistical errors and various kinds of systematical errors).

It's easy to check if the convergence is ~ 1/n or ~ \exp(-a n). So, only a 
limited class of models can describe the data (numbers in the sequence) 
well enough.

By the way, such tricks are often used in mathematics, too (applied 
mathematics, not pure). For example, methods of acceleration of 
convergence. Suppose you have a slowly convergent series, and want to know 
its sum (numerically). Just by summing x_1 + x_2 + ... + x_{1000} + ... 
x_{1000000} + ... + x_{1000000000} + ... you will get the required 
accuracy after 100 years. If you fit your x_n to c_2/n^2 + c_3/n^3 + (a 
few more terms), you will get the same accuracy of the sum in 1 second.

Similar problem was analyzed by Mark Braverman ( he accelerated 
divergence =Giant steps).

./configure options and speed of execution.

Hello, list. By accident i found that maxima built from source with default ./configure options works very slow in comparison with maxima built with this(default archlinux  configure options):
./configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info \ --libexecdir=/usr/lib --enable-sbcl --with-default-lisp=sbcl For example, maxima built with default configure options  needs about 20 seconds to run attached maple_V_N_test.wxm program. Maxima built with default archlinux options takes about 3 seconds to run this program.(Maple, needs 0.89 seconds to run this program(of course, program must be accordingly changed) )

So question is: what is the best ./configure options for program execution speed?

You need to compile the *.mac file, not the  *.wxm file.   A *.wxm file is used by the wxMaxima user interface to
store Maxima code, text, and some formatting
information. If you only have the *.wxm file,  try saving as a *.mac file (File --> Save As).

Ok, there's definitely a bug here. A more minimal example is a .mac file
containing just:

f :(1/2)*exp(-(1/4)*(sqrt(k[1]^2+k[2]^2+k[3]^2)-m)^2 / (sigma)) / (Pi^(3/2));

Chopping the definition down further doesn't seem to trigger it any
more. I haven't time to debug this more completely now, but maybe this
hint will be useful for someone else.

Re: compile_file() error


Compiling an assignment of a symbolic expression to a name will not make 
it run faster.

You can compile a function this way:

  f (x) :=  (1/2)*exp(-(1/4)*(sqrt(k[1]^2+k[2]^2+k[3]^2)-m)^2 / (sigma)) 
/ (Pi^(3/2));

compile(f);

You don't need a separate file, a special command to compile files, a 
separate "compile-time"
operation, etc.  The compiler is there all the time.

You might mean %pi instead of Pi, by the way.

I'm a bit confused about why you wrote this email. The message that you
appear to be replying to (although you don't quote any of it) is from me
and demonstrates the smallest cut-down example that I can make
triggering the bug in the Maxima translator.

It isn't intended to speed up anything.

Most people do not compile files, but individual function definitions.
It is unlikely that any item in your file will benefit from compilation, 
since you
have not declared any types.  Even so, there is nothing to speed up other
than  the increment of the index in for j:0 thru N.   The body of the 
loop consists
of calls to functions that are already as compiled as they can be.

My suggestion is that you ignore compilation unless you are trying to do
numerical calculations, and find that it is too slow.

Bear in mind that you are likely to encounter other bugs in the
Maxima->Lisp translator. Sorry about that.

I can't tell for sure without looking at the .LISP file, but I suspect
the code generated in the .LISP file is not readable: the printing
parameters have been set so that code is not too messy for humans
looking at it. In particular, deeply nested expressions are represented
by # in the output. 

The attached patch disables such measures in the translation code. I'll
push it out for the next Maxima release (August 2012).

Thanks for bringing it to our attention.

Can you tell us what the configure script chooses for its options when
you go for the defaults? For example, which lisp implementation is it
using? If you could attach your config.log, we might be able to work out
what's going on more easily.

Re: ./configure options and speed of execution.

I attached both config.log files. One for default configure options, second for configure with
./configure--prefix=/usr--mandir=/usr/share/man--infodir=/usr/share/info \ --libexecdir=/usr/lib--enable-sbcl--with-default-lisp=sbcl

Great, thanks. It seems that without hints to do otherwise, the
configure script uses clisp as the lisp implementation. I note that in
README.lisps, we have the following:

Maxima devs: Is there a good reason to use Clisp as the default on Linux
boxes? Maybe we could switch to GCL or SBCL (I'd prefer the latter)

Well, the default choice should be one which is widely available,
stable, lacking idiosyncrasies, etc. If you would like to survey the
Lisp world and identify an alternative to Clisp, by all means, please go
ahead. I am willing to second the motion if you are willing to do the
work.

Re: ./configure options and speed of execution.

I second Robert's comment.  Speed is only one consideration among many.  Correctness, error recovery, quality of debugging tools, availability of useful functionality (notably FFI), etc. etc. are all more important. 

For that matter, speed can be measured in many different ways -- speed of large symbolic calculations, speed of (compiled) numerical calculations, interactive responsiveness, speed of graphing functions interactively, etc.  For the vast majority of our users (even power users), I am pretty sure that any of the supported versions is fast enough.  Showing that version A is 3x faster on a benchmark than version B doesn't mean that the user experience is any better on version A.

Apparently SBCL is more "popular":

<https://encrypted.google.com/search?hl=en&q=...>
 SBCL lisp	1,200,000 results
 CMUCL lisp	466,000 results
 CLISP lisp	450,000 results
 GCL lisp	108,000 results
 ECL lisp	19,500 results

and (at least for me) Maxima in SBCL seems to crash less often than in GCL. 

The latest stable release of GCL was in 2005, while SBCL is actively 
maintained, so I guess that (at least on Linux) the order to try 
should be SBCL, CLISP, GCL.

You could try using a Levin transform.

Have a look at the (undocumented) share package share/contrib/levin.  
These often benefit from extended precision, so try the bfloat version too.
