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