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