Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified based convolution algorithms" » "modified based evolution algorithm", "modified based solution algorithm", "modified dilated convolution algorithms", "modified based continuation algorithms", "modified male convolution algorithms"

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 based convolution algorithms") OR ("modified multiobjective estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified based convolution algorithms ) or ( modified multiobjective estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified based convolution algorithms") or ("modified multiobjective estimation algorithm"))*.
