10
12 This is 'bin/nef-4d.x': calculate Hodge numbers of nef-partitions
13
14 Options: -h prints this information
15
16 -f or -
17 use as filter; otherwise parameters denote I/O files
18
19 -N input is in N-lattice (default is M)
20
21 -H gives full list of Hodge numbers
22
23 -Lv prints L vector of Vertices (in N-lattice)
24
25 -Lp prints L vector of Points (in N-lattice)
26
27 -p prints only partitions, no Hodge numbers
28
29 -D calculates also direct products
30
31 -P calculates also projections
32
33 -t full time info
34
35 -cCODIM
36 codimension (default = 2)
37
38 -Fcodim

40
41 -y prints poly/CWS in M lattice if it has nef-partitions
42
43 -S information about #points calculated in S-Poly
44

46
47 -s don't remove symmetric nef-partitions
48
49 -n prints polytope only if it has nef-partitions
50
51 -v prints vertices and #points of input polytope in one line; with
52 -u, -l the output is limited by #points:
53
54 -uPOINTS
55 ... upper limit of #points (default = POINT_Nmax)
56
57 -lPOINTS
58 ... lower limit of #points (default = 0)
59
60 -m starts with [d w1 w2 ... wk d=d_1 d_2 (Minkowski sum)
61
62 -R prints vertices of input if not reflexive
63
64 -V prints vertices of N-lattice polytope
65
66 -Q only direct products (up to lattice Quotient)
67
68 -gNUMBER
69 prints points of Gorenstein polytope in N-lattice
70
71 -dNUMBER
72 prints points of Gorenstein polytope in M-lattice
73
74 if NUMBER = 0 ... no
75 0/1 info
