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