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

Try widening your search to All Fields.

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

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