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 optimized algorithms" » "modified stochastic optimization algorithms", "modified stochastic optimized algorithm", "modified stochastic optimizer algorithms"

Try widening your search to All Fields.

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 convolution algorithms") or ("modified stochastic optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive convolution algorithms") OR ("modified stochastic optimized algorithms")).
• Removing quotes may allow a broader search: (( modified adaptive convolution algorithms ) or ( modified stochastic optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive convolution algorithms") or ("modified stochastic optimized algorithms"))*.
