Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"mapping graining methods algorithm" » "mapping learning methods algorithm", "mapping learning method algorithm", "mapping making 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: (("mapping graining methods algorithm") OR ("modified multiobjective optimizer algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping graining methods algorithm\") OR (\"modified multiobjective optimizer algorithms\"))".
• Removing quotes may allow a broader search: (( mapping graining methods algorithm ) OR ( modified multiobjective optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("mapping graining methods algorithm") OR ("modified multiobjective optimizer algorithms"))*.
