Question

MATLAB如下是不是就代表找到最优解了？

Local minimum found that satisfies the constraints.

Optimization completed because the objective function is non-decreasing in
feasible directions, to within the default value of the function tolerance,
and constraints are satisfied to within the default value of the constraint tolerance.

Answer 1

可以认为得到的局部极小值是最优解。

因为 Local minimum found that satisfies the constraints.  这句提示说明，已得到满足约束条件的局部极小值。

而 Optimization completed because the objective function is non-decreasing in 
feasible directions, to within the default value of the function tolerance,
and constraints are satisfied to within the default value of the constraint tolerance. 这句也提示说明，由于目标函数不减少，优化完成。可行方向，在函数公差的默认值内，约束满足于约束容差的缺省值。
