Perhaps you should try some spelling variations:
"modified parameter optimized algorithmsssssss" » "modified parameter optimized algorithmssssss", "modified parameter optimizer algorithmsssssss", "modified parameter optimization algorithmsssssss"
"modified objective optimized algorithms" » "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimization algorithms", "modified objective optimal 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 algorithmsssssss\") OR (\"modified objective optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( modified parameter optimized algorithmsssssss ) OR ( modified objective optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimized algorithmsssssss") OR ("modified objective optimized algorithms"))*.
