Perhaps you should try some spelling variations:
allocation estimation » allocation optimization, motion estimation
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
parameter optimized » parameter optimization
optimized algorithm » optimized algorithms, optimizer algorithms

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