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