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