I am working on a optimization problem by patternseach. I have a initial guess vector whose objective function is about 13.5. However, when I used the patterensearch, the objective function is 63.59 far from my initial guess; even after 2200 iterations, it is still far from my inital guess. I checked the x0 of patteren search at iter 0 and found it used [1 0 0...] as x0, instead of my inital guess vector or (my inital guess vector + [1 0 0 ...]).
I wish it can search from my initial guess and the range I provided. Are there any good suggestions?
