Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
mppt algorithm » mom algorithm, qspr algorithm
when learning » deep learning, how learning, shot learning

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( when learning mppt algorithm ) OR ( modified parameter optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( when learning mppt algorithm ) OR ( modified parameter optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( when learning mppt algorithm ) OR ( modified parameter optimisation algorithm ))*.
