Perhaps you should try some spelling variations:
"modified bayesian optimisation algorithm" » "modified bayesian optimization algorithms", "modified bayesian estimation algorithm", "modified bayesian estimation algorithms", "modified bayesian optimization algorithm"
"modified adaptive convolution algorithms" » "modified adaptive evolution algorithm", "modified adaptive solution algorithm", "modified adaptive construction algorithms", "modified adaptive ventilation algorithms", "modified passive convolution algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified bayesian optimisation algorithm") OR ("modified adaptive convolution algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified bayesian optimisation algorithm\") OR (\"modified adaptive convolution algorithms\"))*".
• Removing quotes may allow a broader search: (( modified bayesian optimisation algorithm ) OR ( modified adaptive convolution algorithms ))*.
