Perhaps you should try some spelling variations:
"machine learning evolutionary algorithm" » "machine learning evolution algorithm", "machine learning solution algorithm"
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("machine learning evolutionary algorithm") OR ("modified multiobjective optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machine learning evolutionary algorithm\") OR (\"modified multiobjective optimization algorithm\"))".
• Removing quotes may allow a broader search: (( machine learning evolutionary algorithm ) OR ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("machine learning evolutionary algorithm") OR ("modified multiobjective optimization algorithm"))*.
