Perhaps you should try some spelling variations:
convolution algorithms » evolution algorithm, solution algorithm
positive convolution » positive solutions
adaptive estimation » adaptive ventilation, quantile estimation, adaptive quantization
modified adaptive » modified passive
modified positive » modified passive

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified adaptive estimation algorithm ) or ( modified positive convolution algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified adaptive estimation algorithm ) OR ( modified positive convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive estimation algorithm ) or ( modified positive convolution algorithms ))*.
