Perhaps you should try some spelling variations:
"modified exact convolution algorithmss" » "modified exact evolution algorithm", "modified exact evolution algorithms", "modified exact solution algorithms", "modified exact solution algorithmss"
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective convolution algorithms") or ("modified exact convolution algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective convolution algorithms") OR ("modified exact convolution algorithmss"))*.
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) or ( modified exact convolution algorithmss ))*.
