Perhaps you should try some spelling variations:
convolution algorithms » evolution algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
solution algorithm » evolution algorithm, evolutionary algorithm, estimation algorithm
sphere estimation » pose estimation

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( sphere estimation algorithms ) or ( device ((convolution algorithms) OR (solution algorithm)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( sphere estimation algorithms ) OR ( device ((convolution algorithms) OR (solution algorithm)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( sphere estimation algorithms ) or ( device ((convolution algorithms) OR (solution algorithm)) ))".
• Adding a wildcard symbol may retrieve word variants: (( sphere estimation algorithms ) or ( device ((convolution algorithms) OR (solution algorithm)) ))*.
