Perhaps you should try some spelling variations:
"modified objective solution algorithms" » "modified objective solution algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms", "modified objective evolutionary algorithms", "modified objective allocation algorithms"
"modified learning methods algorithm" » "mobile learning methods algorithm", "modified caging methods algorithm", "modified nursing 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 solution algorithms") OR ("modified learning methods algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective solution algorithms\") OR (\"modified learning methods algorithm\"))*".
• Removing quotes may allow a broader search: (( modified objective solution algorithms ) OR ( modified learning methods algorithm ))*.
