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 algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

You may be able to get more results by adjusting your search query.

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