El algoritmo sqp tiene dos nuevos enfoques para la solución de Ecuación 14 cuando no se satisfacen las restricciones. El algoritmo sqp combina las funciones objetivo y de restricción en una función de mérito.
Para obtener ayuda si falla la minimización, consulte Cuando el solver falla o Cuando es posible que el solver haya tenido éxito. Para ejecutar una optimización de nuevo para obtener más velocidad en problemas de tamaño pequeño o mediano, pruebe 'sqp' a continuación y 'active-set' en último lugar.
quadprog finds a minimum for a problem specified by. min x 1 2 x T H x + f T x such that { A ⋅ x ≤ b, A e q ⋅ x = b e q, l b ≤ x ≤ u b. H, A, and Aeq are matrices, and f, b, beq , lb, ub, and x are vectors. You can pass f, lb, and ub as vectors or matrices; see Matrix Arguments. Note.
A SQP algorithm implementation for solving nonlinear constrained optimization problems. Summary of Steps for SQP Algorithm. Make a QP approximation to the original problem. For the first iteration, use a Lagrangian Hessian equal to the identity matrix. Solve for the optimum to the QP problem.
The SQPlab (pronounce S-Q-P-lab) software presented in these pages is a modest Matlab implementation of the SQP algorithm for solving constrained optimization problems. The functions defining the problem can be nonlinear and nonconvex, but must be differentiable.
