在非线性问题的求解中,ceres-solver是很著名的求解器,其核心的算法原理也是SQP,其在步长搜索时使用Wolfe zoom的方法,没有考虑步长是否违反约束的操作,所以其不能求解带约束的非线性问题,但可以把约束放到cost中进行求解,该方法可能存在无解或求解时间长的问题,对此也进行了研究。 非线性问题为,f(x) = \log(1+1...
去掉x这个变量,得到(1)的另一个等价问题: \min \frac{1}{2}x^TPx+ q^Tx+ I_{Ax=z}(x,\tilde{z}) + I_C(z) \tag{7a} subject \quad to \quad \tilde{z} =z\tag{7b} \\ 对(7)列出相应的增广拉格朗日函数: L_{\rho,\sigma}(x,\tilde{z},z,y) = \frac{1}{2}x^TPx+ q^Tx...
The OSQP (Operator Splitting Quadratic Program) solver is a numerical optimization package for solving problems in the form minimize 0.5 x' P x + q' x subject to l <= A x <= u wherex in R^nis the optimization variable. The objective function is defined by a positive semidefinite matrix...
