Perhaps you should try some spelling variations:
allocation optimisation » allocation optimization
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
game estimation » pose estimation, game optimization

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