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

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