.SH "NAME"
compute_ext_rays \- compute extreme rays of a tropical cone
.SH "DESCRIPTION"
Computes the extreme rays of a tropical cone given by a system of tropically
affine inequalities.
.SH "ARGUMENTS"
.TP
\fB\-numerical\-data\fP
Set the type of numerical data used by the algorithm, one of: ocaml_int,
ocaml_float, ocaml_big_int, ocaml_big_rat, zarith_int, and zarith_rat.
.TP
\fB\-min\-plus\fP
Use the min\-plus semiring instead of the default max\-plus semiring.
.TP
\fB\-no\-ordering\fP
The constraints are not dynamically ordered during the execution.
.TP
\fB\-polymake\-output\fP
Output under polymake format.  Takes an argument, corresponding to a list
c_1,...,c_p of coordinates on which the result is projected.
.TP
\fB\-bounding\-box\fP
Set a bounding box, specified as a list (separated by commas) of
triples (c:l:u), where c is the index of a coordinate, and l and u are lower
and upper bounds (\fB\-infinity\fP/\fB+infinity\fP are allowed).
.TP
\fB\-help\fP, \fB\-\-help\fP
Display this list of options.
