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.
