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

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: "(( smooth estimation algorithmss ) OR ( game estimation algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( smooth estimation algorithmss ) OR ( game estimation algorithms ))*.
