Perhaps you should try some spelling variations:
"post optimization algorithms" » "post optimisation algorithm", "post estimation algorithms", "post optimized algorithms", "robust optimization algorithms", "qoe optimization algorithms", "policy optimization algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"
"qoe estimation algorithm" » "pose estimation algorithm", "_ estimation algorithm", "cover estimations algorithm"

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