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