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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("defined network optimized algorithm") OR ("modified multiobjective estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"defined network optimized algorithm\") OR (\"modified multiobjective estimation algorithm\"))*".
• Removing quotes may allow a broader search: (( defined network optimized algorithm ) OR ( modified multiobjective estimation algorithm ))*.
