manual page for cws-11d.x 2.11


cws.x -<options>; the first option must be -w, -c, -i, -d or -h.


This is `cws.x': create weight systems and combined weight systems.

Options: -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.
