Perhaps you should try some spelling variations:
"modified time convolution algorithms" » "modified time solution algorithm", "modified time evolution algorithms", "modified bi1 convolution algorithms", "modified male convolution algorithms"
"modified objective evolution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective solution 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 time convolution algorithms\") OR (\"modified objective evolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified time convolution algorithms ) OR ( modified objective evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified time convolution algorithms") OR ("modified objective evolution algorithm"))*.
