Perhaps you should try some spelling variations:
"post optimisation algorithm" » "post optimization algorithms", "post estimation algorithm", "post estimation algorithms", "robust optimization algorithm", "_ optimisation algorithm", "qoe optimization algorithm"
"qoe optimized algorithms" » "qoe optimized algorithm", "qoe optimizer algorithms", "qoe optimization algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ 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: (((("qoe optimized algorithms") OR ("_ optimized algorithms"))) or ("post optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("qoe optimized algorithms") OR ("_ optimized algorithms"))) OR ("post optimisation algorithm")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"qoe optimized algorithms\") OR (\"_ optimized algorithms\"))) or (\"post optimisation algorithm\"))".
• Removing quotes may allow a broader search: (((( qoe optimized algorithms ) OR ( _ optimized algorithms ))) or ( post optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimized algorithms") OR ("_ optimized algorithms"))) or ("post optimisation algorithm"))*.
