Perhaps you should try some spelling variations:
"qoe optimization algorithms" » "qoe optimisation algorithm", "qoe estimation algorithms", "qoe estimation algorithm", "game optimization algorithms", "_ optimization algorithms", "stage optimization algorithms"
"d_ optimized algorithm" » "d_ optimized algorithms", "d_ optimizer algorithms", "_ optimized algorithm", "_ optimize algorithm", "_ optimise algorithm"
"one optimized algorithm" » "one optimized algorithms", "one optimizer algorithms", "_ optimized algorithm"

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 ("one optimized algorithm"))) OR ("qoe optimization algorithms"))~.
• Removing quotes may allow a broader search: (((( d_ optimized algorithm ) or ( one optimized algorithm ))) or ( qoe optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("d_ optimized algorithm") or ("one optimized algorithm"))) or ("qoe optimization algorithms"))*.
