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 model solution algorithm" » "modified model evolution algorithm", "modified model convolution algorithms", "modified model evolutionary algorithm", "modified male solution algorithm", "modified model solutions algorithm", "modified nodal solution algorithm", "modified model selection algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified model solution algorithm") OR ("modified notion estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified model solution algorithm\") OR (\"modified notion estimation algorithms\"))*".
• Removing quotes may allow a broader search: (( modified model solution algorithm ) OR ( modified notion estimation algorithms ))*.
