Webb28 maj 2024 · Simplex method is an approach to solving linear programming models by hand using slack variables, tableaus, and pivot variables as a means to finding the optimal solution of an optimization problem. WebbThe dual problem of a convex optimization problem can be obtained in a relatively simple and structural way by using a well-known result in convex analysis, namely Fenchel’s duality theorem. This alternative way of forming a strong dual problem is the subject of this paper.

WebbIf we change to soft-margin SVM with slack variable C, and changing the notation of label. We could generate a run time comparison betwenn Primal solution and Dual solution. The run time for Dual solution is almost one-half to the Primal in changing of slack variable or changing sample size, which makes it a more convenient way of solving SVM.
