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