Perhaps you should try some spelling variations:
optimizer algorithms » optimized algorithms, optimization algorithms
objective optimized » objective optimal, objective optimization
optimized algorithm » optimized algorithms
changing optimizer » choosing optimizer
modified changing » modified caging

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified changing optimizer algorithms ) OR ( modified objective optimized algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified changing optimizer algorithms ) OR ( modified objective optimized algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified changing optimizer algorithms ) OR ( modified objective optimized algorithm ))*.
