Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"model using source algorithm" » "model using our algorithm", "model using search algorithm", "model using force algorithm", "model using morse algorithm", "code using source algorithm", "models nursing source algorithm", "powder using source 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 algorithms") OR ("model using source algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimized algorithms\") OR (\"model using source algorithm\"))*".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) OR ( model using source algorithm ))*.
