Perhaps you should try some spelling variations:
"modified early convolution algorithms" » "modified early evolution algorithm", "modified early solution algorithm", "modified early evolution algorithms", "modified learning convolution algorithms", "modified male convolution algorithms", "modified near convolution algorithms"
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation 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 early convolution algorithms\") OR (\"modified objective predation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified early convolution algorithms ) OR ( modified objective predation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified early convolution algorithms") OR ("modified objective predation algorithm"))*.
