Perhaps you should try some spelling variations:
"modified choosing optimization algorithms" » "modified choosing optimisation algorithm", "modified choosing estimation algorithms", "modified choosing estimation algorithm", "modified staffing optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimization algorithms"
"modified objective optimizer algorithmss" » "modified objective optimizer algorithms", "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimal algorithmss", "modified objective optimization algorithmss"

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

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