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