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