Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
objective optimisation » objective optimization, multiobjective optimization
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
charging optimized » choosing optimizer
modified charging » modified caging, modified carbon

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

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