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