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