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