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