Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"active learning method algorithm" » "active learning mom algorithm", "machine learning method algorithm", "active learning methods algorithm", "active graining methods algorithm", "active 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: (("active learning method algorithm") or ("modified multiobjective optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("active learning method algorithm") OR ("modified multiobjective optimized algorithms"))*.
• Removing quotes may allow a broader search: (( active learning method algorithm ) or ( modified multiobjective optimized algorithms ))*.
