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