Did not converge
WebIf the callable returns False for the step length, the algorithm will continue with new iterates. The callable is only called for iterates satisfying the strong Wolfe conditions. Maximum number of iterations to perform. Alpha for which x_new = x0 + alpha * pk , or None if the line search algorithm did not converge. WebApr 3, 2024 · The optimization might not converge, either because the initial guess is poor or because the model is not a good fit to the data. SAS regression procedures for which this might happen include PROC LOGISTIC, GENMOD, MIXED, GLMMIX, and NLMIXED. For mixed models, several problems can occur if you have a misspecified model.

WebMar 26, 2016 · Objective Cell values do not converge. The message tells you that the objective function doesn't have an optimal value. In other words, the objective function keeps getting bigger even though the constraint formulas are satisfied. In other words, Excel finds that it keeps getting a better objective function value with every iteration, but it ...
