Tīmeklis2024. gada 18. marts · Now, I understand we can find the dual problem by first identifying the dual function, which is defined: $$ g(x) = \inf_x \mathcal{L(x,\lambda,\nu)} $$ where $\mathcal{L} $ represents the Lagrangian, and $\lambda$ and $\nu$ are the respective Lagrangian multipliers for the inequality and equality constraints. TīmeklisThe Lagrangian dual problem (Boyd et al., 2004) plays an important role in the theory of convex and ... the dual problem provides a convex relaxation of the non-convex primal problem. For example, the semi-definite programming relaxation of the two-way partitioning problem can be derived from its dual problem (Boyd et al., 2004).
