Perhaps you should try some spelling variations:
approximation algorithm » approximation algorithms
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
adam approximation » _ approximation, one approximation, time approximation
modified adam » modified df, modified near
modified pose » modified male, modified passive

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