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 raw algorithm" » "model using adam algorithm", "model using _ algorithm", "model using mom algorithm", "code using raw algorithm", "models nursing raw algorithm", "powder using raw algorithm", "model using real algorithm", "model using a algorithm", "model using low 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 optimization algorithms\") OR (\"model using raw algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) OR ( model using raw algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") OR ("model using raw algorithm"))*.
