Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
optimized algorithms » optimized algorithm, optimizer algorithms, optimization algorithms
objective estimation » objective optimization, objective allocation
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 optimized algorithms ) OR ( modified objective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified pose optimized algorithms ) or ( modified objective estimation algorithms ))*.
