Perhaps you should try some spelling variations:
optimisation algorithms » optimisation algorithm, optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
adaptive estimation » adaptive ventilation, quantile estimation, adaptive quantization
notion optimisation » network optimization
modified adaptive » modified passive

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