Perhaps you should try some spelling variations:
"designed network optimization algorithmss" » "designed network optimization algorithms", "designed network estimation algorithms", "designed network estimation algorithm", "defined network optimization algorithmss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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 objective optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( designed network optimization algorithmss ) OR ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network optimization algorithmss") OR ("modified objective optimisation algorithm"))*.
