Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"modified graining methods algorithm" » "modified caging methods algorithm", "modified learning methods algorithm", "modified learning method algorithm", "modified 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: (("modified graining methods algorithm") OR ("modified multiobjective estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified graining methods algorithm\") OR (\"modified multiobjective estimation algorithms\"))*".
• Removing quotes may allow a broader search: (( modified graining methods algorithm ) OR ( modified multiobjective estimation algorithms ))*.
