Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
parameter optimisation » parameter optimization, parameter estimation
solution algorithms » solution algorithm, evolution algorithm, convolution algorithms
modified passive » modified adaptive
passive solution » positive solutions, saline solution

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: "(( modified passive solution algorithms ) OR ( modified parameter optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified passive solution algorithms ) OR ( modified parameter optimisation algorithm ))*.
