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

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

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