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