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

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