Perhaps you should try some spelling variations:
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion algorithm"
"modified parameter approximation algorithms" » "modified parameters approximation algorithms"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified learning method algorithm\") OR (\"modified parameter approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified learning method algorithm ) OR ( modified parameter approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning method algorithm") OR ("modified parameter approximation algorithms"))*.
