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