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