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"

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

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