Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified bi1 » modified _
bi1 solution » _ 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 bi1 solution algorithm ) OR ( modified parameter optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified bi1 solution algorithm ) OR ( modified parameter optimisation algorithm ))*.
