Perhaps you should try some spelling variations:
"modified response optimization algorithms" » "modified response optimisation algorithm", "modified response estimation algorithms", "modified response estimation algorithm"
"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"

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