Perhaps you should try some spelling variations:
"modified carbon convolution algorithms" » "modified carbon evolution algorithm", "modified carbon solution algorithm", "modified carbon consumption algorithms", "modified learning convolution algorithms"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified carbon convolution algorithms\") OR (\"modified objective allocation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified carbon convolution algorithms ) OR ( modified objective allocation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified carbon convolution algorithms") OR ("modified objective allocation algorithm"))*.
