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