LevenbergMarquardtNewValueAction Field

If set, the action method is called every time a new x value has been computed. If the x-array argument is changed, the method must return true, otherwise it should return false.

Changing the x-values can be used to constrain the x values to a certain set of values.

Changing the x-values may significantly decrease convergence speed, and it may produce a suboptimal solution, even though an optimal solution is nearby.
