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