Re: [R] Quadratic Constraints

Hi Hans, I am very much thankful to you for helping me to solve the problem. I went through the link provided by you and tried to solve the problem. But I think there's some problem with the code. So it is not arriving at the optimal solution.In Some cases it shows optimum solution while in some

[R] Quadratic Constraints

HI All, I am unable to solve a optimization Problem Please Help Me out of this to solve. The Optimization problem is as follows :- My objective function is linear and one of the constraint is quadratic. Min z = 5 * X1 + 9* X2 + 7.15 *X3 + 2 * X4 subject to X1 + X2 + X3 +X4 = 9 X1 + X4 =

Re: [R] Quadratic Constraints

The package lpSolve (that I have recommended before) supports so-called 'semi-continuous variables', that is Semi-continuous variables are variables that must take a value between their their minimum and maximum or zero. So these variables are treated the same as regular variables,
