Summary 0000401: FIXED: bug in LM optimizer
Description Numerical differentiation version of the LM optimizer implicitly assumed that if you have all variables constrained to one fixed value with constraints like ai<=xi<=ai, then initial value of xi MUST be equal to ai. When this assumption was violated, algorithm converged to the wrong point.
