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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( code based sensor algorithm ) or ( modified parameter optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code based sensor algorithm ) OR ( modified parameter optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( code based sensor algorithm ) or ( modified parameter optimization algorithms ))*.
