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