Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, estimation algorithm, estimation algorithms
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
certified » verified

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( certified network optimization algorithm ) or ( modified objective optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( certified network optimization algorithm ) OR ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( certified network optimization algorithm ) or ( modified objective optimisation algorithm ))*.
