CWS.X

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.
