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