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