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