Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
estimation algorithmss » estimation algorithms, estimation algorithm, optimization algorithms
network optimisation » network optimization
notion estimation » motion estimation
modified network » certified network, defined network, modified near

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 notion estimation algorithmss ) OR ( modified network optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified notion estimation algorithmss ) or ( modified network optimisation algorithm ))*.
