Perhaps you should try some spelling variations:
estimation algorithmss » estimation algorithms, estimation algorithm, optimization algorithms
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified passive » modified adaptive
passive solution » positive solutions, saline solution
modified pose » modified male

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 solution algorithm ) OR ( modified pose estimation algorithmss ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive solution algorithm ) OR ( modified pose estimation algorithmss ))".
• Adding a wildcard symbol may retrieve word variants: (( modified passive solution algorithm ) OR ( modified pose estimation algorithmss ))*.
