Perhaps you should try some spelling variations:
multiobjective optimisation » multiobjective optimization, objective optimization
optimisation algorithm » optimization algorithms, estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
network estimation » network optimization
defined » designed

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

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