/**
 * The LMDIF command minimises the sum of squares of the constraint functions using their numerical derivatives:
 * LMDIF,CALLS=integer,TOLERANCE=real; It is the fastest minimisation method available in MAD. The command has two
 * attributes: CALLS: The maximum number of calls to the penalty function (default: 1000). TOLERANCE: The desired
 * tolerance for the minimum (default: 10**(-6)). Example: LMDIF,CALLS=2000,TOLERANCE=1.0E-8;
