Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
method algorithm » mom algorithm
using lc » using c, using low, using eco
using l » using a, using _, using 3

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((using l) OR (using lc)) method algorithm ) OR ( modified parameters optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((using l) OR (using lc)) method algorithm ) or ( modified parameters optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((using l) OR (using lc)) method algorithm ) or ( modified parameters optimization algorithm ))*.
