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