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