Perhaps you should try some spelling variations:
"modified stochastic optimization algorithms" » "modified stochastic optimisation algorithm", "modified stochastic estimation algorithms", "modified stochastic estimation algorithm"
"modified learning convolution algorithms" » "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithms", "modified caging convolution 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 stochastic optimization algorithms") or ("modified learning convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified stochastic optimization algorithms") OR ("modified learning convolution algorithms")).
• Removing quotes may allow a broader search: (( modified stochastic optimization algorithms ) or ( modified learning convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimization algorithms") or ("modified learning convolution algorithms"))*.
