How get the extreme directions of an unbounded feasible region
$begingroup$
The following constraints form a feasible region.
$-x_1+x_2 le 2$
$-x_1+2x_2 le 6$
$x_1,x_2 ge 0$
The feasible region have three extreme points: $e_1=left[begin{array}{cc}
0\
0
end{array}right]$ $e_2=left[begin{array}{cc}
0\
2
end{array}right]$ $e_3=left[begin{array}{cc}
2\
4
end{array}right]$
What is the procedure that I need to follow to extract the extreme direction from this data?
Extrene Direction: An extreme direction of a convex set is a direction of the set that cannot be represented as a positive combination of two distinct directions of the set.
