Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"machine learning evolutionary algorithm" » "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 optimization algorithm") OR ("machine learning evolutionary algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithm\") OR (\"machine learning evolutionary algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( machine learning evolutionary algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") OR ("machine learning evolutionary algorithm"))*.
