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