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

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

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