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

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