Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective estimation algorithms\") OR (\"model using real algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithms ) OR ( model using real algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithms") OR ("model using real algorithm"))*.
