Perhaps you should try some spelling variations:
"modified objective convolution algorithmss" » "modified objective convolution algorithms", "modified objective evolution algorithm"
"modified multiobjective solution algorithm" » "modified multiobjective evolution algorithm", "modified multiobjective convolution algorithms", "modified multiobjective evolutionary 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 solution algorithm") OR ("modified objective convolution algorithmss"))~.
• Removing quotes may allow a broader search: (( modified multiobjective solution algorithm ) or ( modified objective convolution algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective solution algorithm") or ("modified objective convolution algorithmss"))*.
