Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
objective optimized » objective optimal, objective optimization
optimized algorithm » optimized algorithms, optimizer algorithms
male estimation » pose estimation, pulses estimation

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 male estimation algorithms ) OR ( modified objective optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified male estimation algorithms ) or ( modified objective optimized algorithm ))*.
