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