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 charging convolution algorithms" » "modified charging evolution algorithm", "modified charging solution algorithm", "modified learning convolution algorithms", "modified caging convolution algorithms", "modified carbon 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 charging convolution algorithms\") OR (\"modified parameters optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified charging convolution algorithms ) OR ( modified parameters optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified charging convolution algorithms") OR ("modified parameters optimization algorithm"))*.
