Perhaps you should try some spelling variations:
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ optimization algorithms"
"game estimation algorithm" » "pose estimation algorithm", "game optimization 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: (((("game estimation algorithm") OR ("_ optimization algorithm"))) OR ("_ optimized algorithms"))~.
• Removing quotes may allow a broader search: (((( game estimation algorithm ) or ( _ optimization algorithm ))) or ( _ optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("game estimation algorithm") or ("_ optimization algorithm"))) or ("_ optimized algorithms"))*.
