Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
pre algorithm » mppt algorithm, qspr algorithm, _ algorithm
using pre » nursing pre, using one, using ph
19 using » _ using, ε using

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 19 using pre algorithm ) OR ( modified parameter optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( 19 using pre algorithm ) OR ( modified parameter optimisation algorithm ))*.
