Perhaps you should try some spelling variations:
"modified bayesian optimization algorithms" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "modified bayesian 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 bayesian optimization algorithms\") OR (\"modified charging convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithms ) OR ( modified charging convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimization algorithms") OR ("modified charging convolution algorithms"))*.
