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"
"d_ optimized algorithm" » "d_ optimized algorithms", "d_ optimizer algorithms", "_ optimize algorithm", "_ optimise algorithm"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

You may be able to get more results by adjusting your search query.

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