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