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