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