Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithm", "modified notion optimized algorithms", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified policy estimation algorithms" » "modified policy estimation algorithm", "modified policy optimisation algorithm", "modified policy approximation algorithms", "modified policy optimization algorithms", "modified pose estimation algorithms", "modified motion estimation algorithms"

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 ("modified policy estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion optimization algorithms") OR ("modified policy estimation algorithms")).
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) or ( modified policy estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") or ("modified policy estimation algorithms"))*.
