Perhaps you should try some spelling variations:
"modified over estimation algorithms" » "modified over optimization algorithms", "modified over optimisation algorithm", "modified over approximation algorithms", "modified cover estimations algorithms", "modified pose estimation algorithms", "modified sphere estimation algorithms", "modified near estimation algorithms", "modified orca estimation algorithms"
"modified notion estimation algorithm" » "modified motion estimation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified notion estimation algorithm\") OR (\"modified over estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified notion estimation algorithm ) OR ( modified over estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithm") OR ("modified over estimation algorithms"))*.
