i have a function like 1+sin(a+bx) where -pi/2<=a+bx<=pi/2
i made a progrom using constrOptim() function but it is not giving good result. it depends on the initial value. but when i am doing simulation it is impossible of find the best initial value for every step. also i am not exactly sure how to input the restriction though i have read the help file of the function. here x is a set of values. would u please send me some instruction to find the best result from the obtimization.
