Perhaps you should try some spelling variations:
optimisation algorithmss » optimisation algorithm, optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
static optimisation » static optimization, stage optimization, stochastic optimization
notion estimation » motion estimation

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