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

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

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