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