Perhaps you should try some spelling variations:
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm"
"modified learning emotion algorithm" » "mobile learning emotion algorithm", "modified caging emotion algorithm", "modified learning evolution algorithm", "modified learning estimation algorithm", "modified learning predation algorithm", "modified learning method 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 emotion algorithm") OR ("modified parameters estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified learning emotion algorithm\") OR (\"modified parameters estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified learning emotion algorithm ) OR ( modified parameters estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified learning emotion algorithm") OR ("modified parameters estimation algorithms"))*.
