cws-<num>d.x(1) create weight systems and combined weight systems.

Other Alias



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.


print this information
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).
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.
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'.
compute basic IP weight systems for #-dimensional reflexive Gorenstein cones;
specifies the index as #/2.
adjoin a weight of 1/2 to the input weight system.
make CWS for PPL in N lattice.
