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"
"designed network optimisation algorithm" » "designed network optimization algorithms", "designed network estimation algorithm", "designed network estimation algorithms", "designed network optimization algorithm", "defined network optimisation algorithm"

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

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