Perhaps you should try some spelling variations:
"modified location optimization algorithmss" » "modified location optimization algorithms", "modified location optimisation algorithm", "modified location estimation algorithms", "modified location optimization algorithmsss", "modified location optimisation algorithmss", "modified location estimation algorithmss", "modified allocation optimization algorithmss", "modified static optimization algorithmss", "modified carbon optimization algorithmss"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified location optimization algorithmss") OR ("modified objective optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified location optimization algorithmss\") OR (\"modified objective optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified location optimization algorithmss ) OR ( modified objective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified location optimization algorithmss") OR ("modified objective optimization algorithm"))*.
