First order optimality matlab

WebMay 1, 2024 · I'm not really sure what first-order optimality is in the context of solving a non-linear system though - there's no reason to expect the gradient of the function to go to zero at the zero of the function and no reason to care about it in any case. What am I misunderstanding? 2 Comments 1 older comment Steven Rose on 30 Apr 2024 Sure … Webthe first-order optimality measure is the infinity norm (meaning maximum absolute value) of ∇ f ( x ), which is: This measure of optimality is based on the familiar condition for a smooth function to achieve a minimum: its gradient must be zero. For unconstrained problems, when the first-order optimality measure is nearly zero, the objective ...
