Perhaps you should try some spelling variations:
"modified notion optimisation algorithmss" » "modified notion optimization algorithms", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified notion optimization algorithmsss", "modified notion estimation algorithmss", "modified notion estimation algorithmsss", "modified network optimization algorithmss"
"modified robust optimisation algorithm" » "modified robust optimization algorithms", "modified robust estimation algorithm", "modified robust estimation algorithms", "modified robust optimization algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified robust optimisation algorithm") or ("modified notion optimisation algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified robust optimisation algorithm") OR ("modified notion optimisation algorithmss")).
• Removing quotes may allow a broader search: (( modified robust optimisation algorithm ) or ( modified notion optimisation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified robust optimisation algorithm") or ("modified notion optimisation algorithmss"))*.
