Perhaps you should try some spelling variations:
multiobjective estimation » multiobjective optimization
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
modified time » modified bi1, modified male

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified multiobjective estimation algorithms ) or ( modified time evolution algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified multiobjective estimation algorithms ) OR ( modified time evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified multiobjective estimation algorithms ) or ( modified time evolution algorithm ))*.
