Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"machinery using method algorithm" » "machinery using mom algorithm", "machines using method algorithm", "machinery nursing methods algorithm", "machinery focusing method algorithm", "machinery using metal 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 using method algorithm") OR ("modified objective optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machinery using method algorithm\") OR (\"modified objective optimisation algorithm\"))*".
• Removing quotes may allow a broader search: (( machinery using method algorithm ) OR ( modified objective optimisation algorithm ))*.
