Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"care learning method algorithm" » "care learning mom algorithm", "care learning methods algorithm", "care graining methods algorithm", "care learning emotion algorithm", "based learning method algorithm", "a learning method algorithm", "care planning method 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: (("care learning method algorithm") or ("modified multiobjective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("care learning method algorithm") OR ("modified multiobjective optimization algorithms")).
• Removing quotes may allow a broader search: (( care learning method algorithm ) or ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("care learning method algorithm") or ("modified multiobjective optimization algorithms"))*.
