### Find the optimal solution without going through the ERO's

All I got is that $$12y_1 + 7y_2 + 10y_3 = 2(0) + 4(10.4) + 3(0) + 1(0.4)$$ and $y_2 = 0$ because $x_6$ is in basis. How do I find $y_1$ and $y_3$ without going through the simplex method? I took ...

### How do you find redundant constraints for a feasible region?

I've found a few papers that deal with removing redundant inequality constraints for linear programs, but I'm only trying to find the non-redundant constraints that define a feasible region (i.e. I ...

### Linear Programming constraint equivalent of conditional

I would like to use the following conditional in my linear program: if(A == 1) then B = C + 1 A = binary, B and C are continuous. In the else case, any relation ...
