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