An algorithm for 均衡子问题的一个算法
It has a unique solution and can be easily solved by existing algorithms 此时, qp子问题有唯一解,而且,该问题的求解比较容易。
The second aim of this work is to construct a simpler formulation of newton ' s methods 在大多数qp一free算法中,其子问题的维数通常是满的。
The convergence theorem of the proposed method is proved based on the exact solution of the subproblem 基于子问题的精确求解,该文证明了算法的收敛性。
Moreover , the solution of the qp problem provides a descent direction for most merit functions 另一方面,此时qp子问题的解是许多效益函数的下降方向。
When the hessian is positive definite , the qp subproblem is a strict convex quadratic programming 若qp子问题的hessian阵正定,则它是一个严格凸二次规划问题。
An attractive property of this method is that the hessian of the quadratic objective function is always positive definite 该方案的一个显著优点是qp子问题的目标函数的hessian阵正定。
