Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"enabling learning convolution algorithms" » "enabling learning evolution algorithm", "enabling learning solution algorithm", "mapping learning convolution algorithms"

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

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