Perhaps you should try some spelling variations:
"modified objective optimization algorithmssss" » "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified multiobjective optimization algorithmssss", "modified objective optimization algorithmsssss", "modified objective optimisation algorithmssss", "modified objective estimation algorithmssss"
"modified _ optimization algorithm" » "modified _ optimization algorithms", "modified _ optimisation algorithm", "modified _ estimation 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 objective optimization algorithmssss\") OR (\"modified _ optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimization algorithmssss ) OR ( modified _ optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithmssss") OR ("modified _ optimization algorithm"))*.
