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