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

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ estimation algorithmss\") OR (\"_ estimation algorithms\"))) OR (\"game estimation algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ estimation algorithmss ) OR ( _ estimation algorithms ))) OR ( game estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ estimation algorithmss") OR ("_ estimation algorithms"))) OR ("game estimation algorithm"))*.
