Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"model using real algorithm" » "model using adam algorithm", "model using search algorithm", "code using real algorithm", "models nursing real algorithm", "powder using real algorithm", "model using metal algorithm", "model using raw 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 optimization algorithms") OR ("model using real algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithms\") OR (\"model using real algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) OR ( model using real algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") OR ("model using real algorithm"))*.
