FORMAT OF '.poi' - FILES
The first line contains the dimension of the problem.
DIM = dim
In general, lines consisting of a capitalized keyword are
significant for input recognition. Such keywords can be
COMMENT
CONV_SECTION
CONE_SECTION
END
and function specific keywords (such as ELIMINATION_ORDER).
There is no restriction concerning the order of sections.
The keyword
COMMENT
causes the programs to ignore the text until the next capitalized
keyword occurs. Usually the input contains a set of
points to be considered. If this is missing (the case of
a cone) the origin is assumed to be feasible. The list of
points is started by the keyword
CONV_SECTION
The following lines until the next keyword
contain points, each in one seperate row with exactly dim
rational values, given by numerator and denominator. A
denominator with value 1 can be omitted. A line number in
parantheses at the beginning of the line is
optional:
(ln) num1/den1 num2/den2 ....... numdim/dendim
Also the input may contain a set of vectors spanning
a convex cone. Such a set starts with the keyword
CONE_SECTION
The requirements for the vectors are the same as for points.
END
is needed to terminate the input file.
