Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"how graining methods algorithm" » "how learning methods algorithm", "how learning method algorithm", "how making methods algorithm", "new training methods algorithm", "goi training methods algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("how graining methods algorithm") OR ("modified multiobjective optimizer algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"how graining methods algorithm\") OR (\"modified multiobjective optimizer algorithms\"))".
• Removing quotes may allow a broader search: (( how graining methods algorithm ) OR ( modified multiobjective optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("how graining methods algorithm") OR ("modified multiobjective optimizer algorithms"))*.
