Perhaps you should try some spelling variations:
"modified ohca convolution algorithms" » "modified ohca evolution algorithm", "modified ohca solution algorithm", "modified orca convolution algorithms"
"modified objective optimized algorithms" » "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimization algorithms", "modified objective optimal 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 ohca convolution algorithms") OR ("modified objective optimized algorithms"))~.
• Removing quotes may allow a broader search: (( modified ohca convolution algorithms ) or ( modified objective optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified ohca convolution algorithms") or ("modified objective optimized algorithms"))*.
