Perhaps you should try some spelling variations:
"modified network approximation algorithm" » "modified network approximation algorithms", "certified network approximation algorithm", "defined network approximation algorithm", "modified near 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 network approximation algorithm\") OR (\"modified pose estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified network approximation algorithm ) OR ( modified pose estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network approximation algorithm") OR ("modified pose estimation algorithms"))*.
