Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm
allocation estimation » allocation optimization, motion estimation
estimation algorithms » estimation algorithm, optimization algorithms, approximation 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 ( parameters optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( allocation estimation algorithms ) or ( parameters optimisation algorithm ))*.
