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