Setting Solver Tolerances
Tolerance refers to how small a parameter, such a mesh size, can become before the search is
halted or changed in some way. You can specify the value of the following tolerances
optimoptions or the
Optimize Live Editor task.
MeshTolerance— When the current mesh size is less than the value of
MeshTolerance, the algorithm halts.
StepTolerance— After a successful poll, if the distance from the previous best point to the current best point is less than the value of
StepTolerance, the algorithm halts.
FunctionTolerance— After a successful poll, if the difference between the function value at the previous best point and function value at the current best point is less than the value of
FunctionTolerance, the algorithm halts.
ConstraintTolerance(not a stopping condition) — The algorithm treats a point to be feasible if nonlinear constraint violation is less than
