Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
sensor algorithm » qspr algorithm, search algorithm, winner algorithm
based sensor » gas sensor, based sers

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: (( model based sensor algorithm ) OR ( modified parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( model based sensor algorithm ) or ( modified parameter optimisation algorithm ))*.
