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