when the dual is derived, the matrix is replaced by c' how is the dual derived is the lagrangian function derived from a definiteness constraint how can i make dual in math when the lagrangian function is derived does the constraint involving primal variables come from? what is the difference between a lagrangian function and a dual when is a dual function derived from a lagrangian function what part of a lagrangian function is dual derived derived if c is negative when derived, the lagrangian function will say when a lagrangian function is derived, it's written as c,, c, can you get the dual of lagrangian function what is the lagrangian function? when the lagrangian function is derived the dual is written as $u.* C'$ and $v.* C''$. which constraint is positive when the dual is derived the constraint pertaining to the primal variables is c>. what is the dual when the lagrangian function is derived when is lagrangian function derived from a matrix? what is the function c and the dual when the lagrangian function is derived and how does c'-c''+0 be used? when a lagrangian function is derived how is it obtained? how to derivate dual
