Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"code control a algorithm" » "mode control a algorithm", "case control a algorithm", "order control a algorithm", "code control _ algorithm", "code control _ algorithms", "code control adam algorithm", "code control law algorithm", "code control case 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: (("modified multiobjective optimization algorithm") or ("code control a algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimization algorithm") OR ("code control a algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) or ( code control a algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") or ("code control a algorithm"))*.
