Perhaps you should try some spelling variations:
"modified motion optimization algorithms" » "modified motion optimisation algorithm", "modified motion estimation algorithms", "modified motion estimation algorithm", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified stochastic convolution algorithms" » "modified stochastic configuration algorithms", "modified stochastic evolution algorithm", "modified stochastic solution algorithm"

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