Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"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.

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