Perhaps you should try some spelling variations:
"qoe optimisation algorithms" » "qoe optimisation algorithm", "qoe optimization algorithms", "qoe estimation algorithms", "_ optimisation algorithms", "game optimization algorithms"
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithm"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ optimization algorithms"

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