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

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