BTW - I am trying to capture STDOUT so hence not read a 'file' but passing the string to awk via a pipe. $0 shows the whole string but $1 shows NULL so it doesn't seem to like the delimiters.
eg. I am trying this:
STR="bla bla bla [123] bla bla" #normally the stdout from a command line call of a software product
RUNID=`echo ${STR} | awk -F'[\\[\\]]' '{print $2}'`
echo ${ID}
There's probably a better way to do it but I haven't coded for years.
any ideas?

BTW, if you wanted to use backticks (`) and (") you would need to do this to make it work (not counting Scrutinizer's solution):
which is some terrible abomination to me

Hello,
I have data where words are separated by a delimiter. In this case "="
The number of delimiters in a line can vary from 4to 8. The norm is 4.
Is it possible to have a script where the file could be separated starting with highest number of delimiters and ending with the lowest

HI All,
How to append the multiple delimiters to at end the file up to 69 fields.
FinalDelimiter Count is 69
recrod Delimeter count is 10
so 69-10=59
this script will add upto 59 Delimiters to that records.
this script will check each and every record in a file and append the delimiters... (4 Replies)

pdl::opt::simplex
Simplex(3) User Contributed Perl Documentation Simplex(3)NAME
PDL::Opt::Simplex -- Simplex optimization routines
SYNOPSIS
use PDL::Opt::Simplex;
($optimum,$ssize) = simplex($init,$initsize,$minsize,
$maxiter,
sub {evaluate_func_at($_[0])},
sub {display_simplex($_[0])}
);
DESCRIPTION
This package implements the commonly used simplex optimization algorithm. The basic idea of the algorithm is to move a "simplex" of N+1
points in the N-dimensional search space according to certain rules. The main benefit of the algorithm is that you do not need to calculate
the derivatives of your function.
$init is a 1D vector holding the initial values of the N fitted parameters, $optimum is a vector holding the final solution.
$initsize is the size of $init (more...)
$minsize is some sort of convergence criterion (more...) - e.g. $minsize = 1e-6
The sub is assumed to understand more than 1 dimensions and threading. Its signature is 'inp(nparams); [ret]out()'. An example would be
sub evaluate_func_at {
my($xv) = @_;
my $x1 = $xv->slice("(0)");
my $x2 = $xv->slice("(1)");
return $x1**4 + ($x2-5)**4 + $x1*$x2;
}
Here $xv is a vector holding the current values of the parameters being fitted which are then sliced out explicitly as $x1 and $x2.
$ssize gives a very very approximate estimate of how close we might be - it might be miles wrong. It is the euclidean distance between the
best and the worst vertices. If it is not very small, the algorithm has not converged.
FUNCTIONS
simplex
Simplex optimization routine
($optimum,$ssize) = simplex($init,$initsize,$minsize,
$maxiter,
sub {evaluate_func_at($_[0])},
sub {display_simplex($_[0])}
);
See module "PDL::Opt::Simplex" for more information.
CAVEATS
Do not use the simplex method if your function has local minima. It will not work. Use genetic algorithms or simulated annealing or
conjugate gradient or momentum gradient descent.
They will not really work either but they are not guaranteed not to work ;) (if you have infinite time, simulated annealing is guaranteed
to work but only after it has visited every point in your space).
