Perhaps you should try some spelling variations:
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"
"modified trace solution algorithm" » "modified trace evolution algorithm", "modified trace convolution algorithms", "modified trace evolutionary algorithm", "modified traces solution algorithm", "modified male solution algorithm", "modified orca solution algorithm", "modified exact solution algorithm", "modified nacl solution 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 trace solution algorithm\") OR (\"modified notion estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified trace solution algorithm ) OR ( modified notion estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified trace solution algorithm") OR ("modified notion estimation algorithms"))*.
