Perhaps you should try some spelling variations:
optimization algorithms » estimation algorithms, estimation algorithm, optimized algorithms
optimisation algorithm » estimation algorithm, estimation algorithms
pulses optimisation » pulses estimation
write optimization » game optimization, qoe optimization, stage 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: (( write optimization algorithms ) OR ( pulses optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( write optimization algorithms ) or ( pulses optimisation algorithm ))*.
