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