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