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