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