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

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

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