# cws.x(1)

create weight systems and combined weight systems.

## NAME

cws.x, cws-\<num\>d.x - create weight systems and combined weight systems.

## SYNOPSIS

**cws.x** *-\<options\>*

## DESCRIPTION

The cws-\<num\>d.x variant programs, where \<num\> is one of 4, 5, 6 and 11 work in different dimensions ; cws.x defaults to dimension 6.

Beware: the first option must be -w, -c, -i, -d or -h.

### Options

- **-h**

  print this information

- **-f**

  use as filter; otherwise parameters denote I/O files

- **-w**# \[L H\] make IP weight systems for #-dimensional polytopes.

  For #\>4 the lowest and highest degrees L\<=H are required.

- **-r**/-t make reflexive/transversal weight systems (optional).

  - **-c**#

  make combined weight systems for #-dimensional polytopes. For #\<=4 all relevant combinations are made by default, otherwise the following option is required:

-

  **-n\[**#\] followed by the names wf\_1 ... wf\_# of weight files

-

  currently #=2,3 are implemented.

-

  \[-t\] followed by # numbers n\_i specifies the CWS-type, i.e.

-

  the numbers n\_i of weights to be selected from wf\_i. Currently all cases with n\_i\<=2 are implemented.

- **-i**

  compute the polytope data M:p v \[F:f\] N:p \[v\] for all IP CWS, where p and v denote the numbers of lattice points and vertices of a dual pair of IP polytopes; an entry F:f and no v for N indicates a non-reflexive \`dual pair'.

- **-d**#

  compute basic IP weight systems for #-dimensional reflexive Gorenstein cones;

- **-r**#

  specifies the index as #/2.

- **-2**

  adjoin a weight of 1/2 to the input weight system.

- **-N**

  make CWS for PPL in N lattice.
