Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm"
"modified model solution algorithm" » "modified model evolution algorithm", "modified model evolutionary algorithm", "modified model estimation 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 objective convolution algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified model solution algorithm\") OR (\"modified objective convolution algorithms\"))*".
• Removing quotes may allow a broader search: (( modified model solution algorithm ) OR ( modified objective convolution algorithms ))*.
