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"
"core using method algorithm" » "core using mom algorithm", "core nursing methods algorithm", "core focusing method algorithm", "core using metal algorithm", "code using method algorithm", "care nursing method algorithm"

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

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