Perhaps you should try some spelling variations:
"game optimization algorithms" » "game optimisation algorithm", "game estimation algorithm", "game optimized algorithms", "stage optimization algorithms", "qoe optimization algorithms", "market optimization algorithms"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimisation algorithm", "_ approximation algorithms"
"_ optimize algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm", "_ optimise 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: (((("_ estimation algorithms") OR ("_ optimize algorithms"))) OR ("game optimization algorithms"))~.
• Removing quotes may allow a broader search: (((( _ estimation algorithms ) or ( _ optimize algorithms ))) or ( game optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ estimation algorithms") or ("_ optimize algorithms"))) or ("game optimization algorithms"))*.
