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 topology optimisation algorithm" » "modified topology optimization algorithms", "modified topology estimation algorithm", "modified topology estimation algorithms", "modified topology optimization algorithm", "modified policy optimization algorithm"

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

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