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