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