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"
"powder using real algorithm" » "powder using adam algorithm", "powder using search algorithm", "code using real algorithm", "boiler using real algorithm", "model using real algorithm", "powder using metal algorithm", "powder 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 objective optimization algorithm") OR ("powder using real algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithm\") OR (\"powder using real algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( powder using real algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") OR ("powder using real algorithm"))*.
