This is the command cws.x that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
cws.x, cws-<num>d.x - create weight systems and combined weight systems.
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.
-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.
