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