| 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. | ||||
