Perhaps you should try some spelling variations:
quantile approximation » time approximation, diophantine approximation
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
modified quantile » modified adaptive
game estimation » pose estimation, game optimization
modified game » modified male, modified adam

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