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