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

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

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