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 methods algorithm" » "core nursing methods algorithm", "core making methods algorithm", "core counting methods algorithm", "code using methods algorithm", "care 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: (("core using methods algorithm") OR ("modified multiobjective optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"core using methods algorithm\") OR (\"modified multiobjective optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( core using methods algorithm ) OR ( modified multiobjective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("core using methods algorithm") OR ("modified multiobjective optimisation algorithm"))*.
