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 large evaluation algorithm" » "modified large evolution algorithm", "modified large estimation algorithm", "modified large solution algorithm", "modified large variation algorithm", "modified load evaluation algorithm", "modified based evaluation algorithm", "modified male evaluation 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 large evaluation algorithm\") OR (\"modified notion estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified large evaluation algorithm ) OR ( modified notion estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified large evaluation algorithm") OR ("modified notion estimation algorithms"))*.
