Perhaps you should try some spelling variations:
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
sensor algorithm » qspr algorithm, search algorithm, winner algorithm
based sensor » gas sensor, based sers
code based » model based, coal based, income based

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