I'm pretty new to linear programming and would like a quick tip.
In the script below, what I *want* to happen is that I first choose the
worst (ie: max) of x[p] and 3, and then solve for the minimum sum of these
values.
z[j]>=x[j]
z[j]>=3
ie: I would like z to look like: {1, 2, 3, 3, 3} and then to minimise on the
sum of these.
min SUM z[j]
j
