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 search algorithm" » "model using source algorithm", "model using egarch algorithm", "model nursing research algorithm", "model using servo algorithm", "code using search algorithm", "models nursing search algorithm", "powder using search 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 search algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimized algorithms\") OR (\"model using search algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) OR ( model using search algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithms") OR ("model using search algorithm"))*.
