Perhaps you should try some spelling variations:
"modified make estimation algorithms" » "modified make estimation algorithm", "modified make optimization algorithms", "modified make optimisation algorithm", "modified pose estimation algorithms", "modified male estimation algorithms"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified make estimation algorithms") or ("modified one approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified make estimation algorithms") OR ("modified one approximation algorithms")).
• Removing quotes may allow a broader search: (( modified make estimation algorithms ) or ( modified one approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified make estimation algorithms") or ("modified one approximation algorithms"))*.
