Can any one suggest some material regarding to the Constrained LM Algorithm.

Thanks Amit. But its not Constrained lm. this one is unconstrained algorithm.

Try the attached paper. If you are looking for implementations, there are several packages that deal with simple bounds on variables. Any kind of structure that can be imposed on your constraint will tend to simplify the problem, e.g. (strictly) convex constraint functions, linear constraints, simple upper and lower bounds etc.
