Hi,

I am using R in one of my courses. I am trying to use R's linprog
package to solve to formulate 2-class classification problem as Linear
programming problem.

For my formulation, I need to set to "cvec" to all 0s.
I know the points are linearly separable so an optimal solution "x"
does exist, which satisfies all the constraints.

But given the constraints and setting "cvec" to all 0s it simply gives
me an "x" of all 0s.

How can I fix this?
