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