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