cws.x (1)

cws.x -<options>

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.
