Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
policy estimation » policy optimization, pose estimation, motion estimation
modified passive » modified adaptive

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified passive evolution algorithm ) OR ( modified policy estimation algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive evolution algorithm ) OR ( modified policy estimation algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( modified passive evolution algorithm ) OR ( modified policy estimation algorithms ))*.
