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