Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified multiobjective solution algorithms" » "modified multiobjective solution algorithm", "modified multiobjective evolution algorithm", "modified multiobjective estimation 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 multiobjective solution algorithms") or ("modified objective convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective solution algorithms") OR ("modified objective convolution algorithms")).
• Removing quotes may allow a broader search: (( modified multiobjective solution algorithms ) or ( modified objective convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective solution algorithms") or ("modified objective convolution algorithms"))*.
