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 location estimation algorithms" » "modified location estimation algorithm", "modified location optimisation algorithm", "modified location approximation algorithms", "modified motion estimation algorithms", "modified carbon estimation algorithms"

You may be able to get more results by adjusting your search query.

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