Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
pose optimisation » qoe optimization, _ optimisation, pose estimation
market estimation » market optimization, parameter estimation
modified market » modified male
modified pose » modified male, modified passive

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified pose optimisation algorithm ) OR ( modified market estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified pose optimisation algorithm ) or ( modified market estimation algorithms ))*.
