Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
ph algorithm » _ algorithm, mppt algorithm, qspr algorithm
using ph » using pre, using a, using _
a using » _ using, ε using, 19 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: "(( a using ph algorithm ) OR ( modified parameter optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( a using ph algorithm ) OR ( modified parameter optimisation algorithm ))*.
