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 real algorithm" » "core using adam algorithm", "core using search algorithm", "code using real algorithm", "care nursing real algorithm", "core using metal algorithm", "core using raw algorithm"

Try widening your search to All Fields.

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 real algorithm") or ("modified multiobjective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("core using real algorithm") OR ("modified multiobjective optimisation algorithm")).
• Removing quotes may allow a broader search: (( core using real algorithm ) or ( modified multiobjective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("core using real algorithm") or ("modified multiobjective optimisation algorithm"))*.
