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 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"

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 network approximation algorithm") or ("modified pose optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network approximation algorithm") OR ("modified pose optimization algorithms")).
• Removing quotes may allow a broader search: (( modified network approximation algorithm ) or ( modified pose optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified network approximation algorithm") or ("modified pose optimization algorithms"))*.
