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 changing optimisation algorithm" » "modified changing optimization algorithms", "modified changing estimation algorithm", "modified changing estimation algorithms", "modified staffing optimization algorithm", "modified caging 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 changing optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified adaptive convolution algorithms ) OR ( modified changing optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive convolution algorithms") OR ("modified changing optimisation algorithm"))*.
