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