rsegm --- renormalization of Interval Exchange Transform


SUPPORTED ENVIRONMENTS

GNU/Linux/GMP or GNU/Linux

http://www.gnu.org    GNU/Linux 
http://www.mingw.org  MinGW --- Minimalist GNU For Windows
http://www.swox.com/gmp/ GNU Multiple Precision Library

COMPILATION

There are two variants of installation

1) No multiple precision (for poor men;). Enter 

make -f makefile.nomp (or gmake-f makefile.nomp) 

in the directory where sources reside.

2) With GNU Multiple Precision (GMP). Enter 'make' (or 'gmake') in the
directory where sources reside. The compilation may fail if (a) GMP
library is not installed or (b) C++ wrapper <gmpxx.h> is not
installed. 

In both cases (a) and (b) download GMP library from the address above;

  ./configure --enable-cxx; make; make install

BRIEF INSTRUCTION

Type in 

./rsegm -i10 -d1,2,3,4 -r4,3,1,2 -l0.21321412,0.124909,0.31225291,0.321521

to see the 10th renormalization of interval exchange transformation
with lengths
(lambda_1,lambda_2,lambda_3,lambda_4)=(0.21321412,0.124909,0.31225291,0.321521)

where the domain order of segments is
(d_1,d_2,d_3,d_4)=(1,2,3,4);
and the order of segments in the range is
(r_1,r_2,r_3,r_4)=(4,3,1,2).

The 10th renormalization is
lambda= 0.032077730 0.241342500 0.346696562 0.379883208
d= 1 4 2 3
r= 4 2 3 1

3  Usage and options summary

user@computer$ ./rsegm --help
Usage: rsegm [OPTIONS]
Mandatory arguments to long options are mandatory for short options too
  -d, --domain=ILIST      the order of segments in the domain of transform
  -r, --range=ILIST       the order of segments in the range of transform
  -l, --lambda=DLIST      the lengths of segments (not normalized)
  -i, --iterations=N      do N renormalizations (default N=150)
  -a, --all_info          display complete info
  -p, --precision=P       number of bits per number (def. 64)
  -f, --fprecision=L      Set output format %.Lf
  -g, --gprecision=L      Set output format %.Lg
  -s, --seed-lambda=M     Seed random 'lambda' lengths generator with seed M

The following options are effective when the program is compiled with GNU MP
  -t, --test-permutations Test permutations for inverse transform (adv.)
  -n, --num-perm=N        Output at most N permutations (def. all)
  -b, --back-iterations=N The number of back iterations(def. N=10)
  -S, --seed-precision=R  Set seed precision (otherwise it depends on -p P)

  -q, --quiet             do not send any messages to stderr
  -h, --help              display this help and exit
  -m, --man               display complete description
  -v, --version           display version and exit

Each ILIST is made up of integers, separated by commas
DLIST is made up of real numbers, separated by commas
Default values are -d1,2,3,4 -r4,3,1,2
-l0.21321412312909434390,0.12490902092394324432,0.31225291759028134432,0.32152138238123213124

4  Description

user@computer$ ./rsegm --man
<Usage information from the previous section is omitted>


EXIT CODES

The program exits with code 0, only in case it has done
what it was meant to do. In all other cases the exit code.
is non-zero. For example --help option exits with code
ERROR_HELP. The errors related to interaction with operating
system has code >=16. In future versions more exit codes
can be added, but the current exit code will remain as is.
