Perhaps you should try some spelling variations:
"modified charging convolution algorithms" » "modified charging evolution algorithm", "modified charging solution algorithm", "modified learning convolution algorithms", "modified caging convolution algorithms", "modified carbon convolution algorithms"
"modified objective evolutionary algorithm" » "modified objective evolution algorithm", "modified objective solution algorithm"

Try widening your search to All Fields.

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

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