Perhaps you should try some spelling variations:
"modified multiobjective evolutionary algorithm" » "modified objective evolutionary algorithm", "modified multiobjective evolution algorithm", "modified multiobjective solution algorithm"
"modified objective solution algorithms" » "modified objective solution algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms", "modified objective evolutionary algorithms", "modified objective allocation algorithms"

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 evolutionary algorithm") or ("modified objective solution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective evolutionary algorithm") OR ("modified objective solution algorithms"))*.
• Removing quotes may allow a broader search: (( modified multiobjective evolutionary algorithm ) or ( modified objective solution algorithms ))*.
