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 changing optimized algorithms" » "modified changing optimized algorithm", "modified changing optimizer algorithms", "modified changing optimization algorithms", "modified choosing optimizer algorithms", "modified caging 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 changing optimized algorithms") OR ("modified objective optimizer algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified changing optimized algorithms\") OR (\"modified objective optimizer algorithmss\"))".
• Removing quotes may allow a broader search: (( modified changing optimized algorithms ) OR ( modified objective optimizer algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified changing optimized algorithms") OR ("modified objective optimizer algorithmss"))*.
