Perhaps you should try some spelling variations:
"_ optimizer algorithmss" » "_ optimizer algorithms", "_ optimized algorithms", "_ optimized algorithmss", "_ optimize algorithmss", "_ optimise algorithmss"
"qoe optimized algorithm" » "qoe optimized algorithms", "qoe optimizer algorithms", "_ optimized algorithm"
"risk estimation algorithm" » "pose estimation 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: (("risk estimation algorithm") or ((("qoe optimized algorithm") or ("_ optimizer algorithmss"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("risk estimation algorithm") OR ((("qoe optimized algorithm") OR ("_ optimizer algorithmss")))).
• Removing quotes may allow a broader search: (( risk estimation algorithm ) or ((( qoe optimized algorithm ) or ( _ optimizer algorithmss )))).
• Adding a wildcard symbol may retrieve word variants: (("risk estimation algorithm") or ((("qoe optimized algorithm") or ("_ optimizer algorithmss"))))*.
