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 algorithm" » "modified learning convolution algorithms", "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithm", "modified caging convolution algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified learning convolution algorithm") or ("modified stochastic optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified learning convolution algorithm") OR ("modified stochastic optimization algorithms")).
• Removing quotes may allow a broader search: (( modified learning convolution algorithm ) or ( modified stochastic optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified learning convolution algorithm") or ("modified stochastic optimization algorithms"))*.
