Perhaps you should try some spelling variations:
"modified early convolution algorithms" » "modified early evolution algorithm", "modified early solution algorithm", "modified early evolution algorithms", "modified learning convolution algorithms", "modified male convolution algorithms", "modified near convolution algorithms"
"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"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified early convolution algorithms") OR ("modified parameters estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified early convolution algorithms\") OR (\"modified parameters estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified early convolution algorithms ) OR ( modified parameters estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified early convolution algorithms") OR ("modified parameters estimation algorithms"))*.
