Perhaps you should try some spelling variations:
"modified time approximation algorithm" » "modified time approximation algorithms", "modified one approximation algorithm", "modified _ approximation algorithm", "modified bi1 approximation algorithm", "modified male approximation algorithm"
"modified pose estimation algorithms" » "modified pose estimation algorithm", "modified pose optimization algorithms", "modified pose optimisation algorithm", "modified male estimation algorithms", "modified passive estimation algorithms"

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 pose estimation algorithms\") OR (\"modified time approximation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified pose estimation algorithms ) OR ( modified time approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified pose estimation algorithms") OR ("modified time approximation algorithm"))*.
