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