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

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