Perhaps you should try some spelling variations:
"_ estimation algorithms" » "_ optimization algorithms", "_ optimisation algorithm", "_ approximation 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("_ optimized algorithms") or ("_ estimation algorithms"))) or ("game estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimized algorithms") OR ("_ estimation algorithms"))) OR ("game estimation algorithm")).
• Removing quotes may allow a broader search: (((( _ optimized algorithms ) or ( _ estimation algorithms ))) or ( game estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithms") or ("_ estimation algorithms"))) or ("game estimation algorithm"))*.
