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