Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"course learning method algorithm" » "course learning mom algorithm", "course learning methods algorithm", "course graining methods algorithm", "course learning emotion algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("course learning method algorithm") or ("modified multiobjective optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("course learning method algorithm") OR ("modified multiobjective optimized algorithm"))*.
• Removing quotes may allow a broader search: (( course learning method algorithm ) or ( modified multiobjective optimized algorithm ))*.
