Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithm", "_ optimized algorithms"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimisation algorithm", "_ approximation algorithms"
"game optimized algorithm" » "game optimized algorithms", "game optimizer algorithms", "same optimized algorithm"

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 ("_ optimization algorithms"))) OR ("game optimized algorithm"))~.
• Removing quotes may allow a broader search: (((( _ estimation algorithms ) or ( _ optimization algorithms ))) or ( game optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ estimation algorithms") or ("_ optimization algorithms"))) or ("game optimized algorithm"))*.
