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