Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithm, optimized algorithms
optimization algorithm » optimisation algorithm, estimation algorithm, optimized algorithm
estimation algorithms » estimation algorithm, optimisation algorithm, approximation algorithms
pose » poses, post, jose

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

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