Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "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.

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