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