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