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