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 methods algorithm" » "machine learning methods algorithm", "machinery nursing methods algorithm"

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

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