Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithmss » estimation algorithm, optimization algorithms
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
poses estimation » pose estimation, pulses estimation, cover estimations

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( poses estimation algorithmss ) or ( _ ((estimation algorithms) or (optimisation algorithm)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( poses estimation algorithmss ) OR ( _ ((estimation algorithms) OR (optimisation algorithm)) )).
• Adding a wildcard symbol may retrieve word variants: (( poses estimation algorithmss ) or ( _ ((estimation algorithms) or (optimisation algorithm)) ))*.
