Perhaps you should try some spelling variations:
"modified notion estimation algorithmsss" » "modified notion estimation algorithms", "modified notion estimation algorithm", "modified motion estimation algorithmsss"
"modified df optimisation algorithm" » "modified df optimization algorithms", "modified df estimation algorithm", "modified df estimation algorithms", "modified _ optimisation algorithm", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified adam optimisation algorithm", "modified bi1 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 notion estimation algorithmsss") or ("modified df optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion estimation algorithmsss") OR ("modified df optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified notion estimation algorithmsss ) or ( modified df optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithmsss") or ("modified df optimisation algorithm"))*.
