Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"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"

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