Perhaps you should try some spelling variations:
"modified objective optimizer algorithmssssss" » "modified objective optimizer algorithms", "modified objective optimal algorithmssssss", "modified objective optimization algorithmssssss"
"modified parameter optimized algorithms" » "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter optimization algorithms"

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 parameter optimized algorithms\") OR (\"modified objective optimizer algorithmssssss\"))~".
• Removing quotes may allow a broader search: (( modified parameter optimized algorithms ) OR ( modified objective optimizer algorithmssssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimized algorithms") OR ("modified objective optimizer algorithmssssss"))*.
