Perhaps you should try some spelling variations:
"modified pose optimization algorithms" » "modified pose optimisation algorithm", "modified pose estimation algorithms", "modified pose estimation algorithm", "modified qoe optimization algorithms", "modified game optimization algorithms", "modified response optimization algorithms", "modified male optimization algorithms", "modified passive optimization algorithms"
"modified df approximation algorithm" » "modified df approximation algorithms", "modified _ approximation algorithm", "modified one approximation algorithm", "modified time approximation algorithm", "modified adam approximation algorithm", "modified bi1 approximation 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 df approximation algorithm\") OR (\"modified pose optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified df approximation algorithm ) OR ( modified pose optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified df approximation algorithm") OR ("modified pose optimization algorithms"))*.
