Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified made optimized algorithm" » "modified made optimized algorithms", "modified made optimizer algorithms", "modified male optimized algorithm", "modified adam optimized algorithm", "modified df 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: (("modified multiobjective estimation algorithm") OR ("modified made optimized algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective estimation algorithm\") OR (\"modified made optimized algorithm\"))*".
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) OR ( modified made optimized algorithm ))*.
