Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"
"modified aging convolution algorithms" » "modified aging evolution algorithm", "modified aging solution algorithm", "modified learning convolution algorithms", "modified caging convolution algorithms"

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

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