Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
pose optimisation » qoe optimization, _ optimisation, pose estimation
modified pose » modified male, modified passive
using metal » nursing mental, using medical, using mineral
using real » using raw
code » core

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( code ((using metal) OR (using real)) algorithm ) or ( modified pose optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code ((using metal) OR (using real)) algorithm ) OR ( modified pose optimisation algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code ((using metal) OR (using real)) algorithm ) or ( modified pose optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( code ((using metal) OR (using real)) algorithm ) or ( modified pose optimisation algorithm ))*.
