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

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